Protein
Aldehyde reductase YahK
Organism
Escherichia coli (strain K12)
Function
Catalyzes the reduction of a wide range of aldehydes into their corresponding alcohols. Has a strong preference for NADPH over NADH as the electron donor. Cannot use a ketone as substrate. Is a major source of NADPH-dependent aldehyde reductase activity in E.coli. The in vivo functions of YahK has yet to be determined.
Similarity
Belongs to the zinc-containing alcohol dehydrogenase family.
