ENZYME entry: EC 6.3.2.50

Accepted Name
tenuazonic acid synthetase.
Reaction catalysed
acetoacetyl-CoA + ATP + L-isoleucine <=> AMP + CoA + diphosphate + 2 H(+) + tenuazonic acid
Comment(s)
  • This fungal enzyme, isolated from Magnaporthe oryzae, is an non- ribosomal peptide synthetase (NRPS)-polyketide synthase (PKS) hybrid protein that consists of condensation (C), adenylation (A) and peptidyl-carrier protein (PCP) domains in the NRPS portion and a ketosynthase (KS) domain in the PKS portion.
  • ATP is required for activation of isoleucine, which is then condensed with acetoacetyl-CoA.
  • Cyclization and release from the enzyme are catalyzed by the KS domain.
