Function
[SUCA_PIG] Catalyzes the ATP- or GTP-dependent ligation of succinate and CoA to form succinyl-CoA. The nature of the beta subunit determines the nucleotide specificity (By similarity). [SUCB2_PIG] Catalyzes the GTP-dependent ligation of succinate and CoA to form succinyl-CoA (By similarity).
Publication Abstract from PubMed
Pig GTP-specific succinyl-CoA synthetase is an alphabeta-heterodimer. The crystal structure of the complex with the substrate CoA was determined at 2.1 A resolution. The structure shows CoA bound to the amino-terminal domain of the alpha-subunit, with the free thiol extending from the adenine portion into the site where the catalytic histidine residue resides.
