sucD | succinyl-CoA synthetase, alpha subunit; 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. (312 aa) | ||||
Trad_2623 | GCN5-related N-acetyltransferase; COGs: COG1042 Acyl-CoA synthetase (NDP forming); InterProIPR011761:IPR000182:IPR003781:IPR013650:IPR 016181:IPR016040:IPR016102; KEGG: ami:Amir_1469 CoA-binding domain protein; PFAM: GCN5-related N-acetyltransferase; CoA-binding domain protein; ATP-grasp domain protein; SPTR: C1XWJ3 Acyl-CoA synthetase (NDP forming); PFAM: Acetyltransferase (GNAT) family. (883 aa) | ||||
sucC | succinyl-CoA synthetase, beta subunit; 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. (407 aa) |
