1.3.1.74 |
Accepted name: |
2-alkenal reductase [NAD(P)+] |
Reaction: |
a n-alkanal + NAD(P)+ = an alk-2-enal + NAD(P)H + H+ |
Other name(s): |
NAD(P)H-dependent alkenal/one oxidoreductase; NADPH:2-alkenal α,β-hydrogenase; 2-alkenal reductase |
Systematic name: |
n-alkanal:NAD(P)+ 2-oxidoreductase |
Comments: |
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 detoxication of α,β-unsaturated aldehydes and ketones [cf. EC 1.3.1.102, 2-alkenal reductase (NADP+)]. |
