Malonyl-S-ACP decarboxylase

Malonyl-S-ACP decarboxylase (EC 4.1.1.87, malonyl-S-acyl-carrier protein decarboxylase, MdcD/MdcE, MdcD,E) is an enzyme with systematic name malonyl-(acyl-carrier-protein) carboxy-lyase.^[1]^[2]^[3]^[4]^[5] This enzyme catalyses the following chemical reaction

a malonyl-[acyl-carrier protein] + H⁺

\rightleftharpoons

an acetyl-[acyl-carrier protein] + CO₂

This enzyme comprises the beta and gamma subunits of the enzyme EC 4.1.1.88.
