ID 1.1.1.283 DE methylglyoxal reductase (NADPH). AN lactaldehyde dehydrogenase (NADP(+)). AN methylglyoxal reductase (NADPH-dependent). CA (S)-lactaldehyde + NADP(+) = H(+) + methylglyoxal + NADPH. CC -!- The enzyme from the yeast Saccharomyces cerevisiae catalyzes the CC reduction of a keto group in a number of compounds, forming CC enantiopure products. CC -!- Among the substrates are methylglyoxal (which is reduced to (S)- CC lactaldehyde), 3-methylbutanal, hexane-2,5-dione and 3-chloro-1- CC phenylpropan-1-one. CC -!- The enzyme differs from EC 1.1.1.78 which is found in mammals, by its CC cosubstrate requirement, reaction direction, and enantiomeric CC preference.
