2-alkenal reductase [NAD(P)+];
NAD(P)H-dependent alkenal/one oxidoreductase;
NADPH:2-alkenal alpha,beta-hydrogenase;
2-alkenal reductase
Acting on the CH-CH group of donors;
With NAD+ or NADP+ as acceptor
n-alkanal:NAD(P)+ 2-oxidoreductase
a n-alkanal + NAD(P)+ = an alk-2-enal + NAD(P)H + H+ [RN:R07349 R07350]
R07349 R07350
n-alkanal [CPD:C15596];
NAD+ [CPD:C00003];
NADP+ [CPD:C00006]
alk-2-enal [CPD:C15597];
NADH [CPD:C00004];
NADPH [CPD:C00005];
H+ [CPD:C00080]
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 alpha,beta-unsaturated aldehydes and ketones [cf. EC, 2-alkenal reductase (NADP+)].
