CC -!- FUNCTION: Succinyl-CoA synthetase functions in the citric acid cycle
CC (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of ATP
CC and thus represents the only step of substrate-level phosphorylation in
CC the TCA. The alpha subunit of the enzyme binds the substrates coenzyme
CC A and phosphate, while succinate binding and nucleotide specificity is
CC provided by the beta subunit. {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 -!- 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.
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}.
