physiological function |
sodium-ion pump glutaconyl-CoA decarboxylase is composed of four subunits: GcdA, the carboxytransferase (65 kDa), GcdB, the carboxylyase (36 kDa), GcdC, the biotin carrier (24 kDa) and GcdD (14 kDa) of unknown function. The GcdA subunit catalyzes the biotin-dependent formation of crotonyl-CoA from glutaconyl-CoA |
