2.3.1.252 | a long-chain acyl-CoA + 3 (R)-methylmalonyl-CoA + 6 NADPH + 6 H+ + holo-[mycolipanoate synthase] |
the mycobacterial enzyme accepts long-chain fatty acyl groups from their CoA esters and extends them by incorporation of three methylmalonyl (but not malonyl) residues, forming trimethyl-branched fatty-acids such as (2S,4S,6S)-2,4,6-trimethyltetracosanoate (C27-mycolipanoate). Since the enzyme lacks a thioesterase domain, the product remains bound to the enzyme and requires additional enzyme(s) for removal |
