Protein: Enniatin synthase (Nonribosomal cyclopeptide synthetase ESYN1) [Includes: N-methylcyclopeptide synthetase (EC 6.3.2.-); S-adenosyl-L-methionine-dependent N-methyltransferase (EC 2.1.1.-)] (Q00869)
Organism: Fusarium equiseti (Fusarium scirpi)
Function: Nonribosomal peptide synthetase that synthesizes enniatin by coupling three D-hydroxycarboxylic acids and three L-amino acids via amide and ester bonds in an alternating fashion. Whereas ESYN1 can accept different amino acids as precursors (L -valine, L-isoleucine or L-leucine), only one species of D-hydroxycarboxylic acid can be found in natural enniatin isolates (D-hydroxyisovaleric acid, D-Hiv). D-Hiv stems from L-valine deanimation by a valine aminotransferase to 2-keto-isovaleric acid (2-Kiv), which becomes subsequently reduced by a keto-isovaleric acid reductase (KivR) to D-Hiv. Peptide bond formation and N-methylation of the amino acid occur before three enzyme-bound dipeptidols are condensed to a hexapeptidol.
