CC -!- FUNCTION: Succinyl-CoA synthetase functions in the citric acid cycle
CC (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of
CC either ATP or GTP and thus represents the only step of substrate-level
CC phosphorylation in the TCA. The beta subunit provides nucleotide
CC specificity of the enzyme and binds the substrate succinate, while the
CC binding sites for coenzyme A and phosphate are found in the alpha
CC subunit. {ECO:0000256|HAMAP-Rule:MF_00558}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + CoA + succinate = ADP + phosphate + succinyl-CoA;
CC Xref=Rhea:RHEA:17661, ChEBI:CHEBI:30031, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57287, ChEBI:CHEBI:57292,
CC ChEBI:CHEBI:456216; EC=6.2.1.5; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00558};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=CoA + GTP + succinate = GDP + phosphate + succinyl-CoA;
CC Xref=Rhea:RHEA:22120, ChEBI:CHEBI:30031, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:57287, ChEBI:CHEBI:57292,
CC ChEBI:CHEBI:58189; Evidence={ECO:0000256|HAMAP-Rule:MF_00558};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00558};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00558};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; succinate
CC from succinyl-CoA (ligase route): step 1/1. {ECO:0000256|HAMAP-
CC Rule:MF_00558}.
CC -!- SUBUNIT: Heterotetramer of two alpha and two beta subunits.
CC {ECO:0000256|HAMAP-Rule:MF_00558}.
CC -!- SIMILARITY: Belongs to the succinate/malate CoA ligase beta subunit
CC family. {ECO:0000256|HAMAP-Rule:MF_00558}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00558}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
