Involved in the biosynthesis of volatile esters which confer kiwifruit flavor (PubMed:21450321). Alcohol acyl transferase that can use a wide range of alcohols as substrate to produce esters (PubMed:21450321). Exhibits acetyl-CoA:alcohol O-acyltransferase activity (PubMed:21450321). 2-(methylsulfanyl)acetyl-CoA + butan-1-ol = butyl 2-(methylsulfanyl)acetate + CoA acetyl-CoA + ethanol = CoA + ethyl acetate acetyl-CoA + butan-1-ol = butyl acetate + CoA butan-1-ol + propanoyl-CoA = butyl propanoate + CoA Expressed in fruit. Accumulates in kiwifruit during ripening. Induced by ethylene in ripe fruits. Belongs to the plant acyltransferase family.
