The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balance undetermined; a substrate has a non-numerical coefficient

Enzyme Commission Primary Name: mycocerosate synthase

Enzyme Commission Synonyms: mycocerosic acid synthase

Taxonomic Range: Bacteria

Enzyme Commission Summary:
The enzyme elongates CoA esters of fatty acids from C6 to C20 by incorporation of methylmalonyl, but not malonyl, residues, to form multimethyl-branched fatty-acyl-CoAs such as 2,4,6,8-tetramethyl-octanoyl-CoA.
