Mass balance status: Balanced.

Enzyme Commission Primary Name: malonyl-[acyl-carrier protein] O-methyltransferase

Enzyme Commission Synonyms: BioC

Standard Gibbs Free Energy (ΔrG in kcal/mol): -34.89514Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Involved in an early step of biotin biosynthesis in Gram-negative bacteria. This enzyme catalyses the transfer of a methyl group to the ?-carboxyl group of malonyl-CoA forming a methyl ester. The methyl ester is recognized by the fatty acid synthetic enzymes, which process it via the fatty acid elongation cycle to give pimelyl-[acyl-carried-protein] methyl ester [Lin10].
