Symptoms are more likely to occur during intense isometric exercise (lifting heavy weights) or during less intense but sustained dynamic exercise (walking up stairs). However, intense debate exists regarding the effect of PGAM5 on I/R-related cardiomyocyte death. It's the enzyme that catalyzes the conversion of 3-phosphoglycerate to 2-phosphoglycerate. From the multiple alignments, 114 unambiguously aligned sites were used for the calculation of evolutionary distances. There is no specific treatment. Species that contain two copies of SixA homologs are marked (2) and include α‐proteobacteria Mesorhizobium loti MAFF 303099, Rhizobium etli CFN 42, and Sinorhizobium meliloti 1021 and γ‐proteobacteria Hahella chejuensis KCTC 2396. Another important enzyme recently found to regulate glycolytic branching is PGAM (Hitosugi et al., 2012). This short helix contributes to active site formation by contacting His108 and Ser51. (17) showed that the three activities are not separated during purification procedures. It is this enzyme that catalyzes the conversion of 3-phosphoglycerate to 2-phosphoglycerate. Indeed, the SMART database (Letunic et al., 2006; Schultz et al., 1998) contains a small number (20) of archaeal HPt proteins out of a total of 1444 HPt proteins that contain 1380 bacterial proteins. Kinetic and structural studies have provided evidence that indicate dPGM and bisphosphoglycerate mutase are paralogous structures. 1bq3B:3-189 1bq4B:3-189 1riiA:6-190 Every step in this metabolic pathway is essential to the ultimate production of energy. The properties and kinetics of the 2,3-diphosphoglycerate-dependent phosphoglycerate mutases are discussed. In this mechanism Mn 2+ ions facilitate the transfer of the substrate's phosphate group to Ser62 to form a phosphoserine intermediate. Mark Layton, David Roper, in Dacie and Lewis Practical Haematology (Twelfth Edition), 2017. About 95% of PGAM enzymatic activity in skeletal muscle is attributable to the MM homodimer. 8). Some patients develop fixed weakness with time. We suggest that the ability to generate PGAM5 complexes that have a wide range of phosphatase activities will facilitate screens to identify small molecules that modulate the phosphatase activity of PGAM5. The dPGM superfamily contains a variety of phosphatases exhibiting both broad and narrow substrate specificity. Phospho-fructokinase deficiency can also cause a hemolytic anemia, jaundice, and gouty arthritis, which can be helpful in making the diagnosis. Each sequence is indicated by the source name and the GI number in NCBI. The alignment also shows that active residues Arg7, His8, Arg55, His108, and Ser51 represent common determinant residues for RHG phosphatases containing more distant relatives in addition to SixA homologs. The rat was isolated by the procedure of Scopes (1977) with the modification that PGM was selectively eluted from a final CM-Sephadex column with 1 mM NaI. The high similarity in catalytic properties shown by the enzymes indicates that a single enzyme inhibitor would probably be effective against all nematode enzymes, which supports the development of iPGM as a promising drug target in parasitic nematodes. The bar under the tree corresponds to 0.1 amino acid substitutions/site. J Biol Chem. Serum creatine kinase (CK) levels are increased between episodes of myoglobinuria. There are at least three possible mechanisms for the reaction: (i) a phosphoenzyme (Ping Pong) mechanism; (ii) an intermolecular transfer of phosphate from 2,3-diphosphoglycerate to the substrates (sequential mechanism); (iii) an intramolecular transfer of … Cycle exercise responses in two patients were markedly different from those seen in McArdle disease: the PGAM patients had virtually normal cycle exercise and oxidative capacity, no second wind, and no improvement of their exercise capacity with lipid or lactate supplementation.113, Stefano Sainas, ... Marco L. Lolli, in Annual Reports in Medicinal Chemistry, 2018. This study reports the production, structure, and molecular dynamics analysis of … Phosphoglycerate mutase (2,3-bisphosphoglycerate-independent) Phosphoglycerate mutase catalyses a number of reactions, the most biologically relevant being the interconversion of glycerate-3-phosphate and glycerate-2-phosphate in the glycolysis and gluconeogenesis pathways. Patients often experience acute muscle necrosis and myoglobinuria after exercise, which, if severe, can cause acute renal failure. Phosphoglycerate mutase (PGM) is the specific homotetramer enzyme that catalyzes step 8 of glycolysis transfering the ph… Phosphoglycerate mutase 1 (PGAM1) is a glycolytic enzyme that importantly coordinates glycolysis, pentose phosphate pathway (PPP) flux and serine biosynthesis in cancer cells and hence gains increasing interest of inhibitor discovery. Abstract: Phosphoglycerate mutase 1 (PGAM1) is an important enzyme that catalyzes the reversible conversion of 3-phosphoglycerate and 2-phosphoglycerate during the process of glycolysis. Onset is generally noted as childhood to early adult though some who may be mildly affected by the disorder may not know they have it. In detail, 3PG was found to inhibit the PPP enzyme 6-phosphogluconate dehydrogenase (6PGDH) and 2PG to activate PHGDH (Hitosugi et al., 2012). Moreover, the presence of the last glycine of the RHG motif is not an absolute prerequisite for these enzymes and is frequently replaced with alanine. The statistical significance of the NJ tree topology was evaluated by bootstrap analysis (Felsenstein, 1985) with 1000 iterative tree constructions. The only other tissue containing substantial amounts of the M subunit is sperm, but there is no evidence of cardiomyopathy or infertility in patients with PGAM deficiency. Muscle biopsy was normal in most patients, but diffuse or patchy glycogen accumulation was seen in a few cases (Figure 39.6), and about one-third of patients had tubular aggregates, a finding not shared by any other glycolytic disorder and whose pathogenesis remains obscure. Phosphoglycerate mutase (PGM) catalyzes the isomerization of 3-phosphoglycerate and 2-phosphoglycerate in glycolysis and gluconeogenesis. Muscle phosphoglycerate mutase deficiency (PGAMD) is a metabolic myopathy characterised by exercise-induced cramp, myoglobinuria, and presence of tubular aggregates in the muscle biopsy. Lactate dehydrogenase M subunit deficiency has been reported in three families with exertional myoglobinuria. The disease is not progressive and has an excellent prognosis. Muscle glycogen levels may be normal in the disorders affecting terminal glycolysis, and definite diagnosis is made by assaying the muscle enzyme activity. Anionic molecules such as vanadate,[12] acetate, chloride ion, phosphate, 2-phosphoglycolate, and N-[tris(hydroxymethyl)methyl-2-amino]ethanesulfonate are known inhibitors of the mutase activity of dPGM. Nine of the 13 patients described with this disorder have been African Americans. Peter Tipton, ... Mark Hannink, in Methods in Enzymology, 2018. There are a total of three reactions dPGM can catalyze: a mutase reaction resulting in the conversion of 3PG to 2PG and vice versa,[4][5] a phosphatase reaction creating phosphoglycerate from 2,3-bisphosphoglycerate,[6][7] and a synthase reaction producing 2,3-bisphosphoglycerate from 1,3-bisphosphoglycerate similar to the enzyme bisphosphoglycerate mutase[citation needed]. Serum CK level was increased between attacks. [2] This class of PGM enzyme shares the same superfamily as alkaline phosphatase. PGAM catalyzes the conversion of 3PG into 2-phosphoglycerate (2PG) (Fig. A list of bacteria and archaea in which SixA homologs were found. They catalyze the internal transfer of a phosphate group from C-3 to C-2 which results in the conversion of 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG) through a 2,3-bisphosphoglycerate intermediate. This study reports the production, structure, and molecular dynamics analysis of Bacillus anthracis cofactor-independent PGM (iPGM). [13] Both phosphate and 2-phosphoglycolate are competitive inhibitors of mutase activity in respect to the substrates 2-phosphoglycerate and 2,3-bisphosphoglycerate.[14]. The histidine-bound phosphate is donated to carbon-2 of 3-phosphoglycerate, then the phosphate of carbon-3 is removed by the histidine, leaving 2-phosphoglycerate and phosphohistidine. The symptoms are an intolerance to physical exertion or activity, cramps and muscle pain. It is responsible for the catalytic synthesis of 2,3-Bisphosphoglycerate (2,3-BPG) from 1,3-bisphosphoglycerate.BPGM also has a mutase and a phosphatase function, but these are much less active, in contrast to its glycolitic cousin, phosphoglycerate mutase (PGM), which favors these two … Similarly, in the yeast Candida albicans , phosphoglycerate mutase (Gpmlp) can localize to the cell wall, where it can facilitate binding to host proteins, possibly as a mechanism … Twelve well-verified patients had been described by 2009, nine of whom were African American. The collected amino acid sequences of SixA homologs were aligned by MAFFT (Katoh et al., 2002, 2005) with the NW‐NS‐i option (Fig. Human PGAM requires 2,3-biphosphoglycerate as a cofactor and is a dimeric enzyme containing, in different tissues, different proportions of a slow-migrating muscle isozyme (MM), a fast migrating brain isozyme (BB), and an intermediate hybrid form (MB). A patient with PGAMD who experienced muscle cramps on forearm ischemic exercise testing was protected from cramps by dantrolene, suggesting that cramps in this disease reflect excessive calcium release from the sarcoplasmic reticulum relative to calcium reuptake capacity. In Streptococcus suis, phosphoglycerate mutase binds to host fibronectin and collagen type I . 4pgmB:3-189 3pgmB:3-189 1qhfA:3-189 1c7zA:253-400 1fbtB:253-400 1c81A:253-400, Phosphoglycerate mutase (PGM) is any enzyme that catalyzes step 8 of glycolysis. It catalyzes the internal transfer of a phosphate group from C-3 to C-2 which results in the conversion of 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG) through a 2,3-bisphosphoglycerate intermediate. Multiple alignment of SixA homologs with some well‐characterized RHG phosphatases. [citation needed] PGAM1 deficiency affects the liver, while PGAM2 deficiency affects the muscle. 1t8pA:5-195 1h2eA:2-151 1h2fA:2-151 A similar ultrastructural pattern of glycogen excess is found in all disorders of glycogenolysis and glycolysis. Patients with PGAM deficiency are usually asymptomatic, except when they engage in brief, strenuous efforts which may trigger myalgias, cramps, muscle necrosis and myoglobinuria. 2B). Avoidance of strenuous exercise prevents acute attacks of muscle cramps and myoglobinuria. Glycolysis is a 10-step process that invests energy in the initial stages only to recover greater amounts of energy in the final steps. Muscle Nerve 2013; 47:138. This aliphatic residue may be characteristic of SixA and is not conserved in Ais, as is the case with Asp18 and Arg21. Isolated myopathy with intolerance of vigorous exercise, cramps, and myoglobinuria has been reported in a few patients with PGK deficiency. Phosphoglycerate mutase. Phosphoglycerate mutase (PGM) is an enzyme that catalyzes step 8 of glycolysis. ... • Mechanism of reoxidizing NADH in fermenting microorganisms The initial patient described in 1981 1 and 9 of the 13 patients described thus far have been African Americans. All six enzyme defects cause symptoms and signs of muscle energy impairment similar to those of the types V and VII GSD. Allosteric regulation is considered to be an innovative strategy to discover a highly selective and potent inhibitor targeting PGAM1. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Moreover, these phosphatases seem to be abundant in microbial genomes. (16) and Kappel et al. Within the SixA family, most members of each of the three proteobacteria are clustered. Residual glycolysis is sufficient to support normal aerobic capacity so there is no evidence of substrate-limited oxidative metabolism. If these individuals slow or rest briefly at the onset of symptoms, they can resume exercising at the original pace. PGAM deficiency reduces muscle enzyme activity to about 5% of normal and causes premature fatigue, contractures, and rhabdomyolysis with myoglobinuria triggered by maximal effort exercise. They catalyze the internal transfer of a phosphate group from C-3 to C-2 which results in the conversion of 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG) through a 2,3-bisphosphoglycerate intermediate. Phosphoglycerate mutase does not readily release glycerate-2,3-P2 (19). This trend in SixA distribution may be correlated with the distribution of HPt proteins. In the E. coli SixA structure, Gly9 contacts with Leu23, which is strictly limited to leucine or isoleucine in the RHG phosphatases. 1bif :251-398 1k6mB:253-400 1c80A:253-400 Two copies of SixA homologs of three species in α‐proteobacteria are separated into two groups that form roughly two clusters, while two copies of SixA homologs of Hahella chejuensis in γ‐proteobacteria are distantly separated from each other and from any copy of α‐proteobacteria. [3], PGM is an isomerase enzyme, effectively transferring a phosphate group (PO43−) from the C-3 carbon of 3-phosphoglycerate to the C-2 carbon forming 2-phosphoglycerate. The mm-type is found mainly in smooth muscle almost exclusively. Figure 39.6. [§ 1]. [citation needed]. The alignment reveals that Asp18 and Arg21 are well conserved in SixA homologs but not within others. 8. Sequence data with significant similarity to E. coli SixA were collected following database searches using BLAST with E‐value <0.001 and PSI‐BLAST employing five iterations with E‐value <0.005 at the NCBI site (http://www.ncbi.nlm.nih.gov/blast/psiblast.cgi). Michio Hirano MD, in Neurobiology of Disease, 2007. Phosphoglycerate kinase deficiency is an X-linked disorder manifesting with varying combinations of hemolytic anemia, seizures, mental retardation, and exercise intolerance with myoglobinuria. Phosphoglycerate mutase (PGM) is any enzyme that catalyzes step 8 of glycolysis. Generally speaking, mutases are enzymes that catalyze the shift of a functional group between two similar positions of a molecule. These archaeal HPt proteins are chemotaxis sensor kinases rather than ArcB homologs. Acta Neuropathol 2009; 117:723. The three-dimensional structure of B. anthracis PGM is composed of two structural and functional domains, the … In humans the PGAM2 gene which encodes this enzyme is located on the short arm of chromosome 7. Two distinct types of PGM exist in nature, one that requires 2,3-bisphosphoglycerate as a cofactor (dPGM), and another that does not (iPGM), as it is structurally distinct and possesses different mechanisms of action. Additional cases have been identified, and a number of mutations identified in the responsible. In the subsequent phosphotransferase part of the reaction, the phosphate group is transferred from Ser62 to the O2 or O3 positions of the reoriented glycerate to yield the PGA product. Click on genes, proteins and metabolites below to link to respective articles. Phosphoglycerate mutase 1 (PGAM1) plays a pivotal role in cancer metabolism and tumor progression via its metabolic activity and interaction with other proteins like α-smooth muscle actin (ACTA2). Like phosphoglucomutase (20), it does not form free enzyme with each turnover but regenerates E- P. In contrast, bisphosphoglycerate synthase is limited by the rate of phosphorylation (6). An electron micrograph shows focal excess of electron-dense (dark) glycogen particles in a subsarcolemmal zone (arrowheads) and within the cytoplasm. Sasa- ki et al. Bootstrap probability of a cluster is only shown at the root node of the cluster when the value is equal to or greater than 50%. Aromatic (W, F, Y) residues are colored red, aliphatic (V, L, I, M) pink, acidic and amide (D, E, N, Q) blue, basic (K, R, H) green, cysteine (C) yellow, and others (S, T, P, G, A) gray. Toshio Hakoshima, Hisako Ichihara, in Methods in Enzymology, 2007. Phosphoglycerate mutase (PGM) catalyzes the isomerization of 3-phosphoglycerate and 2-phosphoglycerate in glycolysis and gluconeogenesis. Phosphoglycerate mutase exists primarily as a dimer of two either identical or closely related subunits of about 32kDa. The co-factor dependent phosphoglycerate mutase (dPGM) is found in a dimeric active conformation in Escherichia coli (E.coli). 2,3-bisphosphoglycerate is required a cofactor for dPGM. [9] When 3-phosphoglycerate enters the active site, the phosphohistidine complex is positioned as to facilitate transfer of phosphate from enzyme to substrate C-2 creating a 2,3-bisphosphoglycerate intermediate. Nematodes possess the iPGM form, whereas mammals have dPGM. Each genus name is assigned + or − to indicate the presence or absence, respectively, of a SixA homolog. In work by Dhamodharan et al.,78 an analysis of partial genomic and amino acid sequences and the phylogenetic tree of W. bancrofti (Wb-iPGM), the major causative agent of human lymphatic filariasis, indicated that this gene, apart from being a potential drug target, could also provide diagnostic, taxonomical, and evolutionary markers. The mb-isozyme is found in cardiac and skeletal muscle and the bb-type is found in the rest of tissues. One exception is Ais, which lacks this insertion. Phophoglycerate mutase 1 (PGAM1) is an enzyme that catalyzes the interconversion of 3‐phosphoglycerate and 2‐phosphoglycerate during glycolysis. The enzyme is found in organisms as simple as yeast through Homo sapiens and its structure is highly conserved throughout. Six additional enzyme defects produce muscle glycogenoses, namely, deficiencies in phosphoglycerate kinase, phosphoglycerate mutase, lactate dehydrogenase, fructose-1,6-bisphosphate aldolase A, pyruvate kinase, and β-enolase. [6] Both enzymes are contained in the superfamily that also contains the phosphatase portion of phosphofructokinase 2 and prostatic acid phosphatase. These enzymes are categorized into the two distinct classes of either cofactor-dependent (dPGM) or cofactor-independent (iPGM). All patients had intolerance to intense exercise, with myalgia and cramps, and about half of them had recurrent myoglobinuria. As reported previously (Rigden, 2003), SixA forms a monophyletic cluster distant from other families, including the Ais family. Such similarities make such enzymes promising drug target in parasitic nematodes. Prepares molecule for subsequent dehydration which will generate a "high-energy" phosphoryl compound for ATP synthesis. Following alignment of the collected sequences by MAFFT (Katoh et al., 2002, 2005), alignment was slightly modified by visual inspection. Joshi PR, Knape M, Zierz S, Deschauer M. Phosphoglycerate mutase deficiency: case report of a manifesting heterozygote with a novel E154K mutation and very late onset. Cell Metabolism Article A Novel Allosteric Inhibitor of Phosphoglycerate Mutase 1 Suppresses Growth and Metastasis of Non-Small-Cell Lung Cancer KeHuang,1,10 QianLiang,2,3,10 YeZhou,2,3,10 Lu-luJiang,1 Wei-mingGu,2,3 Ming-yuLuo,2,3 Ya-binTang,2,3 YangWang,2,3 Wei Lu,4 Min Huang,5 Sheng-zhe Zhang,6 Guang-lei Zhuang,6 Qing Dai,7 Qian-cheng Shen,8 Jian Zhang,8 Hui-min Lei,2,3 Mutations in the genes encoding the enzymes have been identified in all four of these disorders. Reaction mechanism Phosphoglucomutase affects a phosphoryl group shift by exchanging a phosphoryl group with the substrate. SixA homologs were found within bacteria, and a total of 98 putative homologs of E. coli SixA were identified from bacteria and archaea for the following analyses (Fig. Phosphoglycerate mutases (PGMs) catalyze the isomerization of 2- and 3-phosphoglycerates and are essential for glucose metabolism in most organisms. 7. Marco Sciacovelli, ... Christian Frezza, in Methods in Enzymology, 2014. [citation needed] This presents as a metabolic myopathy and is one of the many forms of syndromes formerly referred to as muscular dystrophy. Purpose: Necroptosis is an important form of cell death following myocardial ischemia/reperfusion (I/R) and phosphoglycerate mutase 5 (PGAM5) functions as the convergent point for multiple necrosis pathways. Phosphoglycerate mutase (PGM) is any enzyme that catalyzes step 8 of glycolysis. [11] While all three isozymes may be found in any tissue, the above distributions are based on prevalence in each. [15] An unusual pathologic feature of PGAM deficiency is the association with tubular aggregates. [1] The dPGM enzyme (EC 5.4.2.11) is composed of approximately 250 amino acids and is found in all vertebrates as well as in some invertebrates, fungi, and bacteria. Patients with McArdle disease experience a “second wind” phenomenon. 1ebbA:2-151 2bifA:251-398 3bifA:251-398 E. coli SixA possesses a conserved aliphatic residue, Leu79, which should be essential in forming 310‐helix H4 within this short β3‐H5 loop. Phosphoglycerate mutase deficiency (glycogenosis type X). FIET caused decreased but not absent venous lactate response. Since it is a reversible reaction, it is not the site of major regulation mechanisms or regulation schemes for the glycolytic pathway. In the cofactor-dependent enzyme's initial state, the active site contains a phosphohistidine complex formed by phosphorylation of a specific histidine residue. For clarity, each genus contains one representative species. 1. Six additional enzyme defects produce muscle glycogenoses, namely, deficiencies in phosphoglycerate kinase, Diseases Associated with Primary Abnormalities in Carbohydrate Metabolism, Swaiman's Pediatric Neurology (Sixth Edition). 3 | CATALYTIC MECHANISM OF PGAM1 PGAM1 is a brain isoform of phosphoglycerate mutase. PGAM is a dimeric enzyme containing muscle (M), brain (B) or both subunits in different tissues. Two distinct types of PGM exist in nature, one that requires 2,3-bisphosphoglycerate as a cofactor (dPGM), and another that does not (iPGM), as it is structurally distinct and possesses different mechanisms of action. Three enzyme defects affecting the terminal glycolysis pathway have been reported, involving phosphoglycerate kinase, phosphoglycerate mutase, and lactate dehydrogenase. Isotopic labeling experiments have confirmed that this reaction proceeds through a glucose 1,6-bisphosphate intermediate. We searched putative homologs of E. coli SixA from bacteria, archaeal, fungi, and yeast. Certain salts, such as KCl, are known to be competitive inhibitors in respect to 2-phosphoglycerate and mutase activity. Normal mature muscle contains predominantly the MM homodimer.101 Liver, kidney, and brain contain mainly the BB form, and heart contains all three dimer types, MM, BB, and MB. An unrooted NJ tree of SixA and some well‐characterized RHG phosphatases. In this chapter, we describe methods for obtaining both multimeric and dimeric complexes of PGAM5 and for characterizing their kinetic properties. Members of the RHG phosphatase family Ais, PhoE, and dPGM were included in the alignment to define characteristic residues of SixA phosphatases. The Wb-iPGM isoform-1 gene encodes an ORF of 515 amino acids and is found to share 96.0% amino acid sequence identity with the iPGM of O. volvulus. The evolutionary distance between every pair of aligned sequences was calculated as the maximum likelihood (ML) estimate (Felsenstein, 1996) using the JTT model (Jones et al., 1992) for the amino acid substitutions. Thus, these two residues are determinant residues for SixA homologs. The failure of blood lactate to increase in response to exercise is a useful diagnostic test and can be used to differentiate muscle glycogenoses from disorders of lipid metabolism, such as carnitine palmitoyl transferase II deficiency and very long chain acyl-CoA dehydrogenase deficiency, which also cause muscle cramps and myoglobinuria. Understanding how the phosphatase activity of PGAM5 is regulated will provide new insight into signaling mechanisms that link changes in cell physiology with mitochondrial function. Every step is catalyzed by one or more enzymes that enhance the rate of the given reaction.
