| Other name(s): |
malonyl-S-ACP decarboxylase; malonyl-S-acyl-carrier protein decarboxylase; MdcD/MdcE; MdcD,E; malonyl-[acyl-carrier-protein] carboxy-lyase |
| Systematic name: |
malonyl-[holo malonate decarboxylase acyl-carrier protein] carboxy-lyase |
| Comments: |
This enzyme comprises the β and γ subunits of EC 4.1.1.88, biotin-independent malonate decarboxylase but is not present in EC 7.2.4.4, biotin-dependent malonate decarboxylase. It follows on from EC 2.3.1.187, acetyl-S-ACP:malonate ACP transferase, and results in the regeneration of the acetylated form of the acyl-carrier-protein subunit of malonate decarboxylase [5]. The carboxy group is lost with retention of configuration [3]. |
