ID   1.3.1.74
DE   2-alkenal reductase.
AN   NAD(P)H-dependent alkenal/one oxidoreductase.
AN   NADPH:2-alkenal alpha,beta-hydrogenase.
CA   n-alkanal + NAD(P)(+) = alk-2-enal + NAD(P)H.
CC   -!- Highly specific for 4-hydroxy-non-2-enal and non-2-enal.
CC   -!- 2-alkenals of shorter chain have lower affinities.
CC   -!- Exhibits high activities also for 2-alkenones such as but-3-en-2-one
CC       and pent-3-en-2-one.
CC   -!- Inactive with cyclohex-2-en-1-one and 12-oxophytodienoic acid.
CC   -!- Involved in the detoxification of alpha,beta-unsaturated aldehydes
CC       and ketones.
