The present invention is directed to a process for the production of alkyl alkanoate wherein a polypeptide that has alcohol acetyl transferase activity (AAT) and has in its three-dimensional structure an alpha-beta hydrolase fold and an active site comprising a serine, histidine, and optionally aspartic acid is, used to convert: - C3-C10 alkanol and acetyl coenzyme A or, - C1-C10 alkanol with C3-C10 acyl coenzyme A, or - Methanol with acetyl coenzyme A, into an alkyl alkanoate. The process is further directed to the use of a recombinant expression vector or plasmid or host cell comprising the nucleotide sequence encoding the polypeptide. The polypeptides according to the invention are genes isolated from Kluyveromyces marxianus, Kluyveromyces lactis, Wickerhamomyces ciferrii, Cyberlindnera jadinii, Hanseniaspora uvarum, Eremothecium cymbalarie and Saccharomyces cerevisiae.
