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       nucleotide specificity is provided by the beta subunit.
CC       {ECO:0000255|HAMAP-Rule:MF_01988}.
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_01988};
CC   -!- PATHWAY: Carbohydrate metabolism; tricarboxylic acid cycle; succinate
CC       from succinyl-CoA (ligase route): step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_01988}.
CC   -!- SUBUNIT: Heterotetramer of two alpha and two beta subunits.
CC       {ECO:0000255|HAMAP-Rule:MF_01988}.
CC   -!- SIMILARITY: Belongs to the succinate/malate CoA ligase alpha subunit
CC       family. {ECO:0000255|HAMAP-Rule:MF_01988}.
