Enzyme Information

1.1.1.265
3-methylbutanal reductase.
based on mapping to UniProt Q12068
3-methylbutanol + NAD(P)(+) = 3-methylbutanal + NAD(P)H.
-!- The enzyme purified from Saccharomyces cerevisiae catalyzes the reduction of a number of straight-chain and branched aldehydes, as well as some aromatic aldehydes.
1.1.1.283
Methylglyoxal reductase (NADPH).
based on mapping to UniProt Q12068
(S)-lactaldehyde + NADP(+) = 2-oxopropanal + NADPH.
-!- The enzyme from the yeast Saccharomyces cerevisiae catalyzes the reduction of a keto group in a number of compounds, forming enantiopure products. -!- Among the substrates are methylglyoxal (which is reduced to (S)- lactaldehyde), 3-methylbutanal, hexane-2,5-dione and 3-chloro-1- phenylpropan-1-one. -!- The enzyme differs from EC 1.1.1.78 which is found in mammals, by its coenzyme requirement, reaction direction, and enantiomeric preference.
