EC - Methylglyoxal reductase (NADPH)

  IntEnz view ENZYME view

IntEnz Enzyme Nomenclature


Accepted name:
methylglyoxal reductase (NADPH)
Other names:
lactaldehyde dehydrogenase (NADP+)
GRE2 (gene name)
methylglyoxal reductase (NADPH-dependent)
lactaldehyde:NADP+ oxidoreductase
Systematic name:
(S)-lactaldehyde:NADP+ oxidoreductase



The enzyme from the yeast Saccharomyces cerevisiae catalyses 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) [1,2], 3-methylbutanal [3], hexane-2,5-dione [4] and 3-chloro-1-phenylpropan-1-one [5]. The enzyme differs from EC, methylglyoxal reductase (NADH), which is found in mammals, by its coenzyme requirement, reaction direction, and enantiomeric preference.
