ID   7.2.4.5
DE   glutaconyl-CoA decarboxylase.
AN   4-carboxybut-2-enoyl-CoA carboxy-lyase.
AN   glutaconyl coenzyme A decarboxylase.
AN   pent-2-enoyl-CoA carboxy-lyase.
CA   (2E)-glutaconyl-CoA + H(+) + Na(+)(in) = (2E)-butenoyl-CoA + CO2 +
CA   Na(+)(out).
CC   -!- The enzyme from the bacterium Acidaminococcus fermentans is a
CC       biotinyl-protein, requires Na(+), and acts as a sodium pump.
CC   -!- Prior to the Na(+)-dependent decarboxylation, the carboxylate is
CC       transferred to biotin in a Na(+)-independent manner.
CC   -!- The conserved lysine, to which biotin forms an amide bond, is located
CC       34 amino acids before the C-terminus, flanked on both sides by two
CC       methionine residues, which are conserved in every biotin-dependent
CC       enzyme.
CC   -!- Formerly EC 4.1.1.70.
