Ligands: ACT, COA, EDO Related: 6mgg Activity: Succinate--CoA ligase (ADP-forming), with EC number 6.2.1.5 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [A0A454XSD0_FRATT] Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.[HAMAP-Rule:MF_01988][RuleBase:RU000699] [SUCC_FRATT] Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.
