glutaconyl-CoA decarboxylase M-CSA #675 | Bacterial Glutaconyl-CoA decarboxylase is an unusual ion transport holozyme, which uses the free energy released from the decarboxylation of glutaconyl CoA to crotonyl CoA in order to power the active transport of sodium ions into the periplasm. The carboxyl transferase subunit, GCDalpha is responsible for the first step in this process whereby the transfer of carbon dioxide to the biotin cofactor on GCDalpha is carried out. This subunit displays structural homology to the family of crotonases such as methylmalonoyl CoA decarboxylase, but little sequence identity, so although it clearly shares a common ancestor, divergence is likely to have occurred a long time in the past. | Defined by 4 residues: VAL:A-152 [auth A-151]GLY:A-195 [auth A-194]ILE:B-418 [auth B-417]ALA:B-458 [auth B-457] | EC: 4.1.1.70 (PDB Primary Data) EC: 7.2.4.5 (UniProt) |
