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 catalyses EC 184.108.40.206, benzyl alcohol O-benzoyltransferase.
