IUBMB Enzyme Nomenclature


Accepted name: methylglyoxal reductase (NADPH)

Reaction: (S)-lactaldehyde + NADP+ = methylglyoxal + NADPH + H+

Glossary: methylglyoxal = 2-oxopropanal

Other name(s): lactaldehyde dehydrogenase (NADP+); GRE2 (gene name); methylglyoxal reductase (NADPH-dependent); lactaldehyde:NADP+ oxidoreductase

Systematic name: (S)-lactaldehyde:NADP+ oxidoreductase

Comments: The enzyme from the yeast Saccharomyces cerevisiae catalyses the reduction of a keto group in a number of compounds, forming enantoiopure 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]. It differs in cosubstrate requirement from EC, methylglyoxal reductase (NADH), which is found in mammals.
