What is the function of this protein?
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 (PubMed:7601090, PubMed:10887181).  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) (PubMed:7601090, PubMed:10887181).  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 (PubMed:7601090, PubMed:10887181).  Peptide bond formation and N-methylation of the amino acid occur before three enzyme-bound dipeptidols are condensed to a hexapeptidol (PubMed:7601090, PubMed:10887181).
What are the official names of this protein?
Enniatin synthase, Nonribosomal cyclopeptide synthetase ESYN1.
What is the protein family that this protein belongs to?
Belongs to the ATP-dependent AMP-binding enzyme family.
