CC -!- FUNCTION: Succinyl-CoA synthetase functions in the citric acid
CC cycle (TCA), coupling the hydrolysis of succinyl-CoA to the
CC synthesis of either ATP or GTP and thus represents the only step
CC of substrate-level phosphorylation in the TCA. The beta subunit
CC provides nucleotide specificity of the enzyme and binds the
CC substrate succinate, while the binding sites for coenzyme A and
CC phosphate are found in the alpha subunit. {ECO:0000255|HAMAP-
CC 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:0000255|HAMAP-
CC Rule:MF_00558};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00558};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00558};
CC -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle;
CC succinate from succinyl-CoA (ligase route): step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_00558}.
CC -!- SUBUNIT: Heterotetramer of two alpha and two beta subunits.
CC {ECO:0000255|HAMAP-Rule:MF_00558}.
CC -!- SIMILARITY: Belongs to the succinate/malate CoA ligase beta
CC subunit family. {ECO:0000255|HAMAP-Rule:MF_00558}.
