FAMILY

succinate/malate CoA ligase beta subunit family

DESCRIPTION

Also known as SUCC_FRATT, sucC. Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit. Heterotetramer of two alpha and two beta subunits.
