ID 2.3.1.252 DE mycolipanoate synthase. AN mycolipanoic acid synthase. CA 3 (S)-methylmalonyl-CoA + a long-chain fatty acyl-CoA + 9 H(+) + holo- CA [mycolipanoate synthase] + 6 NADPH = 3 CO2 + 4 CoA + 3 H2O + long-chain CA mycolipanoyl-[mycolipanoate synthase] + 6 NADP(+). CC -!- This mycobacterial enzyme accepts long-chain fatty acyl groups from CC their CoA esters and extends them by incorporation of three CC methylmalonyl (but not malonyl) residues, forming trimethyl-branched CC fatty-acids such as (2S,4S,6S)-2,4,6-trimethyl-tetracosanoate (C27- CC mycolipanoate). CC -!- Since the enzyme lacks a thioesterase domain, the product remains CC bound to the enzyme and requires additional enzyme(s) for removal. DR A0A089QRB9, MSL3_MYCTU ; //
