Accepted name: methylglyoxal reductase (NADH)
Reaction: (R)-lactaldehyde + NAD+ = 2-oxopropanal + NADH + H+
Glossary: 2-oxopropanal = methylglyoxal
Other name(s): methylglyoxal reductase; D-lactaldehyde dehydrogenase; methylglyoxal reductase (NADH-dependent)
Systematic name: (R)-lactaldehyde:NAD+ oxidoreductase
Comments: This mammalian enzyme differs from the yeast enzyme, EC, methylglyoxal reductase (NADPH-dependent), by its coenzyme requirement, reaction direction, and enantiomeric preference.
