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   -!- 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}.
