ENZYME entry: EC 2.3.1.295

PURL: https://purl.expasy.org/enzyme/EC/2.3.1.295
Accepted Name
mycoketide-CoA synthase
Reaction catalysed
a medium-chain fatty acyl-CoA + 5 (S)-methylmalonyl-CoA + 5 malonyl-CoA + 22 NADPH + 32 H(+) = a mycoketide-CoA + 10 CO2 + 22 NADP(+) + 10 CoA + 11 H2O
Comment(s)
  • The enzyme, found in mycobacteria, is involved in the synthesis of beta-D-mannosyl phosphomycoketides.
  • It is a very large polyketide synthase that contains two complete sets of FAS-like fatty acid synthase modules.
  • It binds an acyl-CoA with 5-9 carbons as a starter unit, and extends it by five rounds of alternative additions of malonyl-CoA and methylmalonyl-CoA extender units.
  • Depending on the starter unit, the enzyme forms mycoketide-CoAs of different lengths.
