1.3.1.74 |
2-alkenal reductase (NAD(P)(+)).
based on mapping to UniProt Q39172
A n-alkanal + NAD(P)(+) = an alk-2-enal + NAD(P)H.
-!- Highly specific for 4-hydroxynon-2-enal and non-2-enal. -!- Alk-2-enals of shorter chain have lower affinities. -!- Exhibits high activities also for alk-2-enones such as but-3-en-2-one and pent-3-en-2-one. -!- Inactive with cyclohex-2-en-1-one and 12-oxophytodienoic acid. -!- Involved in the detoxification of alpha,beta-unsaturated aldehydes and ketones (cf. EC 1.3.1.102).
