succinyl coenzyme a synthetase

This xenobiotic structural analogue to succinate carries a sulfino group instead of the carboxyl group in succinate, and it is converted to 3SP-CoA in vivo (26). The .gov means its official. However, our patient also developed progressive liver disease with intermittent liver failure, which only temporarily responded to anaplerotic therapy with aspartate. SUCLG2 is GTP-specific and SUCLA2 is ATP-specific, while SUCLG1 encodes the common -subunit. As mentioned above, the activation of itaconate, as well as that of 3SP, was shown for SucCDAm (26). Nucleotide synthesis is an anabolic mechanism generally involving the chemical reaction of phosphate, pentose sugar, and a nitrogenous base. In addition to the compounds succinate, itaconate, 3SP, l-malate, and d-malate, CoA-thioester formation with fumarate, glutarate, and adipate was verified with the same LC/ESI-MS method established by Dalluge et al. 1). Eur J Biochem 241: 779786, Welch EM, Jacobson A 1999 An internal open reading frame triggers nonsense-mediated decay of the yeast SPT10 mRNA. Kinetic data suggest that all enzymes strongly preferred the physiological substrates CoA, ATP, and succinate.

The enzyme is able to use ATP as well as GTP as a cosubstrate (15). The pH was kept at 6 by addition of HCl during the reaction. HHS Vulnerability Disclosure, Help 2013. Subunit interaction during catalysis. Instead, -ketoglutarate is decarboxylated to form succinic semialdehyde, which is subsequently oxidized to form succinate. 1982 Jul;70(1):219-26. doi: 10.1104/pp.70.1.219. mass. Wilkins MR, Gasteiger E, Bairoch A, Sanchez JC, Williams KL, Appel RD, Hochstrasser DF. In this case, the vector-specific Shine-Dalgarno sequence was used. The eluents used were an ammonium acetate buffer (50 mM, pH 5.0) adjusted with acetic acid (eluent A) and 100% (vol/vol) methanol (eluent B). There was no spasticity, no consistent dystonia, and no clinical liver disease. Secondarily reflecting these metabolites were the elevations in glutamine, proline, and alanine. SucCDAbo has not been investigated yet. Rat liver 6-phosphofructo 2-kinase/fructose 2,6-bisphosphatase: a review of relationships between the two activities of the enzyme. Similar to the milder affected patient with the missense mutation, our patient developed severe and ultimately fatal muscle disease with weakness, hypotonia, muscle atrophy, and respiratory failure. Protein production by auto-induction in high density shaking cultures, Enzymatic and chemical synthesis of 3-sulfinopropionic acid, an analog of succinic acid. Kinetic parameters determined for SucCDBL21, SucCDAm, and SucCDAboHisa. Fatal infantile lactic acidosis: Defective SCS has been implicated as a cause of fatal infantile lactic acidosis, which is a disease in infants that is characterized by the build-up of toxic levels of lactic acid. [10]. Nucleoside-diphosphate kinases are enzymes that catalyze the exchange of terminal phosphate between different nucleoside diphosphates (NDP) and triphosphates (NTP) in a reversible manner to produce nucleotide triphosphates. The reaction mechanism as determined by initial rate studies, Malate adenosine triphosphate lyase. Methods Cell Biol 80: 437463, Saada A 2004 Deoxyribonucleotides and disorders of mitochondrial DNA integrity. In an initial attempt to purify SucCDAbo, it was expressed from the vector pET-23a(+)::sucCDAbo (Table 1). Similar phenotype has been described in other causes of liver-based mtDNA depletion syndromes such as caused by mutations in DGUOK and MPV17. A succinyl coenzyme A synthetase preparation from Escherichia coli has the following characteristics: apparent chromatographic, sedimentation, and electrophoretic homogeneity; molecular weight of about 141,000; A 280 (1 mg per ml) = 0.511; higher specific activity than previous preparations; and identity by several criteria with a phosphorylated protein (E-P) obtained upon exposure to Mg . This is similar to previous patients. [7] This histidine residue becomes phosphorylated during the succinate forming step in the reaction mechanism. Euglena gracilis cells synthesize the key tetrapyrrole precursor, -aminolevulinic acid (ALA), by two routes: plastid ALA is formed from glutamate via -, Anal Biochem. 2005. Cells from 50- to 500-ml cultures were harvested by centrifugation (20 min, 4C, 4,000 g) and stored at 20C until use. The gel was stained with Coomassie brilliant blue R. After expression and purification of SucCD enzymes, the enzyme activity was determined by using a continuous spectrophotometric assay, as described in the Material and Methods section. A submersion method for culture of hydrogen-oxidizing bacteria: growth physiological studies. Federal government websites often end in .gov or .mil. [8], Crystal structures for the E. coli SCS provide evidence that the coenzyme A binds within each -subunit (within a Rossmann fold) in close proximity to a histidine residue (His246). Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. Vmax values for both enantiomeric forms of malate were of the same order of magnitude and comparable to the Vmax of the physiological substrate itaconate (Fig. The reverse reaction leading from succinate to succinyl-CoA is important in the reductive citric acid cycle in many bacteria, as well as part of heme biosynthesis and ketone body activation in higher organisms (10). Nonetheless, the other kinetic parameters in this study were in good accordance with published data for SucCDAm (26). Bethesda, MD 20894, Web Policies However, mammalian mitochondrial SCSs are active as dimers and do not form a heterotetramer. asukaensis is linked with the production of asukamycin. The auxiliary enzymes were tested to ensure that they were not rate limiting. The standard in vitro activity of succinate-CoA ligase in the direction of ADP formation was assayed by a continuous spectrophotometric assay according to the method of Cha and Parks (50). Succinyl-CoA - Wikipedia Liver has primarily GDP-linked activity with the SUCLG2 encoded beta-subunit, and heart and kidney have fairly equal amounts of ADP and GDP-linked activities (24). 1). Lane 1, 10 g purified SucCD from E. coli; lane 2, 10 g purified SucCD from A. mimigardefordensis DPN7T; lane 3, 10 g of purified SucCD from A. borkumensis SK2; lanes M, molecular mass standard (PageRuler prestained protein ladder; Thermo Fisher Scientific, Rockford, IL). 1961. (26). 3SP was synthesized as described by Jolls-Bergeret (38); the procedure was modified by one repetition of the step for alkaline cleavage of the intermediate bis-(2-carboxyethyl)sulfone, as described earlier (29). 3), as observed by ESI/MS, is shown as an example in Fig. Succinyl-coenzyme A synthetase activity was detected in extracts of dark- and light-grown wild-type and nongreening mutant cells. 2002 Sep;51(9):2669-76. doi: 10.2337/diabetes.51.9.2669. Correspondence to Four new derivatives of the broad-host-range cloning vector pBBR1MCS, carrying different antibiotic-resistance cassettes, Colloidal dispersion of chloroplast material, Succinyl coenzyme A synthetase from Escherichia coli. The matrix was equilibrated with 50 mM Tris-HCl (pH 7.4) and 0 mM NaCl at a flow rate of 4 ml/min. and transmitted securely. 1972. This enzyme is a tetramer (molecular weight . Since all SucCD enzymes were able to activate 3SP to 3SP-CoA, we consequently demonstrated that the activation of 3SP is not a unique characteristic of the SucCD from A. mimigardefordensis DPN7T. An Acclaim 120 C18 reversed-phase LC column (4.6 by 250 mm, 5 m, with 120 pores) was used to separate the CoA-thioesters at 30C. Besides these kinetic data obtained by Hersh (55), malate-CoA ligases show similarities to SucCD enzymes concerning the amino acid sequence (51), subunit distribution, and molecular weight (53). Measurements of succinate, itaconate, malate, and 3SP were carried out at 30C in the presence of 50 mM Tris-HCl (pH 7.4), 0.4 mM ATP, 0.1 mM CoA, 7 mM MgCl2, 2 mM phosphoenolpyruvate, and 0.1 mM NADH, together with 6 U of pyruvate kinase and 6 U of lactate dehydrogenase from rabbit muscle (Sigma) as auxiliary enzymes. Many NDP serve as acceptor while NTP are donors of phosphate group. SucCDAm showed an approximately 3.6-fold higher Km value for 3SP than that indicated previously (26). Wbbeler JH, Bruland N, Kretschmer K, Steinbchel A. All purification steps were performed at 4C. Characterization of nucleoside-diphosphate kinase from Pseudomonas aeruginosa: complex formation with succinyl-CoA synthetase. However, when we compared the amino terminus of the predicted human SUCLG1 coding region with the amino terminus of the predicted SUCLG1 coding regions of chimpanzee, rat, and mouse (Fig. The PCR product was ligated into the pJet1.2 blunt vector.

This has been related to the interaction of the succinyl-CoA ligase with nucleoside diphosphate kinase gene and imbalances in nucleotide triphosphates has been proposed, but not yet proven, as the cause for mtDNA depletion and subsequent dysfunction of respiratory chain enzyme activities, similar to other mtDNA depletion disorders (15). The https:// ensures that you are connecting to the All these data suggest that these two enzyme subsubclasses, succinate-CoA ligase (EC 6.2.1.4 and 6.2.1.5) and malate-CoA ligase (EC 6.2.1.9), share the same evolutionary origin. Mostly consuming tissues such as heart and brain have more ATP-specific succinyl-CoA synthetase (ATPSCS), while synthetic tissues such as kidney and liver have the more GTP-specific form (GTPSCS). GTP could be replaced with ATP. Succinyl Coenzyme A synthetase (SCS) Succinyl CoA in Citric Acid Cycle. [3] The enzyme facilitates the coupling of this reaction to the formation of a nucleoside triphosphate molecule (either GTP or ATP) from an inorganic phosphate molecule and a nucleoside diphosphate molecule (either GDP or ADP). However, mammalian mitochondrial SCSs are active as dimers and do not form a heterotetramer. Disclaimer. Instead, alpha-ketoglutarate is decarboxylated to form succinic semialdehyde, which is subsequently oxidized to form succinate. 8600 Rockville Pike 1976 May 7;72:248-54 At 3 mo of age, the liver showed levels of mtDNA decreased by 50% compared with controls (ratio of mtDNA/nuclear DNA: patient 2.1, controls 4.23 0.8). The functionalization was performed over a period of 3 days. 1999. Before DNA Cell Biol 23: 797806, Claros MG, Vincens P 1996 Computational method to predict mitochondrially imported proteins and their targeting sequences. It appears that tissue typically involved in anabolic metabolism (like the liver and kidneys) express G-SCS, whereas tissue involved in catabolic metabolism (like the brain, the heart, and muscular tissue) express A-SCS. Supported by National Science Foundation grant DCB91-03253. For complementation experiments with A. mimigardefordensis DPN7T strains, precultures grown in the presence of 20 mM gluconate were used to inoculate the main cultures (50 mM DTDP), resulting in an optical density (600 nm) of 0.1. d-Malic acid of high-purity grade (Chemical Abstracts Service [CAS] registry number 636-61-3) was purchased from Alfa Aeser (Karlsruhe, Germany), and l-malic acid of high-purity grade (CAS registry number 97-67-6) was purchased from Applichem (Darmstadt, Germany). 67 nucleotides downstream of this AUG), which then results in premature translation termination and which would make the mRNA substrate for the so-called nonsense-mediated mRNA decay (or NMD) pathway (17,18), a cellular quality-control mechanism, which results in destabilization of the mRNA (18,19). Generally, these enzymes hydrolyze a nucleoside 3,5-cyclic phosphate to a nucleoside 5-phosphate: Nucleic acid metabolism is a collective term that refers to the variety of chemical reactions by which nucleic acids are either synthesized or degraded. describe two isoforms of succinyl-CoA synthetase in mammals, one that specifies synthesis of ATP, and one that synthesises GTP.[10]. Stock solutions (500 mM) of the respective compounds were prepared in 50 mM Tris-HCl and were neutralized prior to application. The exact binding location of succinate is not well-defined. Oxford University Press is a department of the University of Oxford. In mammals, the enzyme is a heterodimer of an - and a -subunit. Succinyl Coenzyme A Synthetase - an overview - ScienceDirect For SucD subunits, the following sequence similarities were determined: SucDBL21/SucDAm, 55% identical (71% similar) amino acid residues; SucDBL21/SucDAbo, 84% identical (90% similar) amino acid residues; and SucDAm/SucDAbo, 54% identical (73% similar) amino acid residues. Would you like email updates of new search results? However, this grasp domain is located about 35 away from the phosphorylated histidine residue. HHS Vulnerability Disclosure, Help Brain 130: 853861, Carrozzo R, Dionisi-Vici C, Steuerwald U, Lucioli S, Deodato F, Giandomenico SD, Bertini E, Franke B, Kluijtmans LA, Meschini MC, Rizzo C, Piemonte F, Rodenburg R, Santer R, Santorelli FM, Van Rooij A, Vermunt-de Koning D, Morava E, Wevers RA 2007 SUCLA2 mutations are associated with mild methylmalonic aciduria, Leigh-like encephalomyopathy, dystonia and deafness. National Library of Medicine The SucD subunit was provided with a hexahistidine tag at the C terminus. These results indicate that succinyl-coenzyme A synthetase is present in Euglena cells. studies) suggest that co-operative interactions between alternatingly functional active sites on the two halves of the E. coli enzyme contribute to its catalytic efficacy. Thus, the c.40A>T mutation in fact would prevent proper translation initiation at this site. Hence, the cis double bond of maleate (in contrast to a trans double bond in fumarate) might also impair proper binding to the active site. showed that with this plasmid, an efficient gene expression is achieved with the endogenous promoter independent of the orientation of the gene (28). Succinyl Coenzyme A - an overview | ScienceDirect Topics PMC Information on genomic sequences was obtained from the Integrated Microbial Genomes nameplate (https://img.jgi.doe.gov/cgi-bin/er/main.cgi) (44). The greatest flexibility was shown for long-chain fatty acid CoA ligases (EC 6.2.1.3) (16), but acetate-CoA ligases (17, 18), a propionate-CoA ligase (19), and a butyrate-CoA ligase (20) were also shown to react with more than one carbon acid substrate. The lysate obtained from cells of E. coli BL21(DE3)/pLysS expressing either sucCDAbo or sucCDAboHis led to similar results concerning the level of expression of sucCD as well as the specific activity of SucCD, and the results indicate that SucCD from A. borkumensis SK2 might, in general, have comparably low activity. PMC Proteins were eluted by a linear gradient with increasing NaCl concentrations at a flow rate of 1 ml/min, as follows: 0 to 40 min, 0 mM NaCl; 40 to 110 min, a linear gradient of 0 to 1 M NaCl (change in concentration [], 14.3 mmol/min); and 110 to 160 min, 1 M NaCl. Although M. extorquens AM1 possesses both the mtkAB and sucCD genes in its genome (44), it was shown that mtkAB is essential for growth on C1 and C2 compounds, because an insertion mutant lacking intact mtkA did not grow on these compounds. 1982 Jul 5;143(2):237-40 These primers serve as substrates for the synthesis of Okazaki fragments.
