ENZYME entry: EC

Accepted Name
Methanol O-anthraniloyltransferase.
Reaction catalysed
Anthraniloyl-CoA + methanol <=> CoA + O-methyl anthranilate
  • The enzyme from Concord grape (Vitis labrusca) is solely responsible for the production of O-methyl anthranilate, an important aroma and flavor compound in the grape.
  • The enzyme has a broad substrate specificity, and can use a range of alcohols with substantial activity, the best being butanol, benzyl alcohol, iso-pentanol, octanol and 2-propanol.
  • It can use benzoyl-CoA and acetyl-CoA as acyl donors with lower efficiency.
  • In addition to O-methyl anthranilate, the enzyme might be responsible for the production of ethyl butanoate, methyl-3-hydroxy butanoate and ethyl-3-hydroxy butanoate, which are present in large quantities in the grapes.
  • Also catalyzes EC
