ENZYME entry: EC 2.3.1.86

Accepted Name
fatty-acyl-CoA synthase system.
Alternative Name(s)
fatty-acyl-CoA synthase.
yeast fatty acid synthase.
Reaction catalysed
acetyl-CoA + 2n H(+) + n malonyl-CoA + 2n NADPH <=> a long-chain fatty acyl-CoA + n CO2 + n CoA + H2O + 2n NADP(+)
Comment(s)
  • The enzyme from yeasts (Ascomycota and Basidiomycota) is a multi- functional protein complex composed of two subunits.
  • One subunit catalyzes the reactions EC 1.1.1.100 and EC 2.3.1.41, while the other subunit catalyzes the reactions of EC 2.3.1.38, EC 2.3.1.39, EC 4.2.1.59, EC 1.3.1.10 and EC 1.1.1.279.
  • The enzyme differs from the animal enzyme (EC 2.3.1.85) in that the enoyl reductase domain requires FMN as a cofactor, and the ultimate product is an acyl-CoA (usually palmitoyl-CoA) instead of a free fatty acid.
