Succinate--CoA ligase [GDP-forming] subunit beta

UniProtKB accession:  P25126

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 (By similarity). Can use either ATP or GTP, but prefers GTP (PubMed:22751660).
