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 alpha subunit of the enzyme binds the
CC substrates coenzyme A and phosphate, while succinate binding and
CC specificity for either ATP or GTP is provided by different beta
CC subunits. {ECO:0000256|HAMAP-Rule:MF_03222}.
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_03222};
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; EC=6.2.1.4; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_03222};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; succinate
CC from succinyl-CoA (ligase route): step 1/1. {ECO:0000256|HAMAP-
CC Rule:MF_03222}.
CC -!- SUBUNIT: Heterodimer of an alpha and a beta subunit. Different beta
CC subunits determine nucleotide specificity. Together with the ATP-
CC specific beta subunit SUCLA2, forms an ADP-forming succinyl-CoA
CC synthetase (A-SCS). Together with the GTP-specific beta subunit SUCLG2
CC forms a GDP-forming succinyl-CoA synthetase (G-SCS).
CC {ECO:0000256|HAMAP-Rule:MF_03222}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000256|HAMAP-Rule:MF_03222}.
CC -!- SIMILARITY: Belongs to the succinate/malate CoA ligase alpha subunit
CC family. {ECO:0000256|HAMAP-Rule:MF_03222,
CC ECO:0000256|RuleBase:RU000677}.
