Reaksi ini dikatalisis dalam arah sebaliknya. Aktivitas ini biasanya dikaitkan dengan aktivitas butanadiol dehidrogenase (EC 1.1.1.4 atau EC 1.1.1.76). Sementara aktivitas butanadiol dehidrogenase bersifat reversibel, aktivitas diasetil reduktase bersifat ireversibel. Enzim ini telah dilaporkan ada pada khamirSaccharomyces cerevisiae. Enzim ini berbeda dari EC 1.1.1.304, diasetil reduktase (pembentuk (S)-asetoin).
