alcohol acetyltransferase I (ATF1)
Alcohol acetyltransferase I (ATFI) encodes the enzyme alcohol acetyltransferase I (AATase I), which produces acetate esters from acetyl CoA and alcohols. It was obtained from S. cerevisiae.
Usage and Biology
We will be interested in using AATase I to catalyze the reaction: isoamyl alcohol -> isoamyl acetate. Isoamyl acetate is a volatile ester with a strong banana-like scent. (The related enzyme AATase II, which is encoded by the gene ATF2, performs a similar function...but it is less efficient.)
According to studies done by [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12937998&query_hl=16&itool=pubmed_docsum Horton et al.], the addition of 10mM isoamyl alcohol to cultured E. coli expressing the ATF1 gene yields 1.8mM isoamyl acetate after 40 hours.
