2.3.1.84 isoamylalcohol + acetyl-CoA Saccharomyces cerevisiae alcohol acetyltransferase 2 is probably the key enzyme in a steroid detoxification mechanism, alcohol acetyltransferase 1 accounts for 80% of isoamyl acetate production and 30% of ethyl acetate production and might be involved in fatty acid metabolism isoamyl acetate + CoA
