Summary

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 alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and specificity for either ATP or GTP is provided by different beta subunits.
Catalytic Activity
ATP + CoA + succinate = ADP + phosphate + succinyl-CoA
CoA + GTP + succinate = GDP + phosphate + succinyl-CoA
Subunit
Heterodimer of an alpha and a beta subunit. Different beta subunits determine nucleotide specificity. Together with an ATP-specific beta subunit, forms an ADP-forming succinyl-CoA synthetase (A-SCS). Together with a GTP-specific beta subunit forms a GDP-forming succinyl-CoA synthetase (G-SCS).
Similarity
Belongs to the bacterial ribosomal protein bL20 family.
Belongs to the succinate/malate CoA ligase alpha subunit family.
