Malonate decarboxylase gamma subunit
This family consists of several bacterial malonate decarboxylase gamma subunit proteins. Malonate decarboxylase of Klebsiella pneumoniae consists of four different subunits and catalyses the conversion of malonate plus H+ to acetate and CO2. The catalysis proceeds via acetyl and malonyl thioester residues with the phosphribosyl-dephospho-CoA prosthetic group of the acyl carrier protein (ACP) subunit. MdcD and E together probably function as malonyl-S-ACP decarboxylase.
