Reaction: (R)-lactaldehyde + NAD+ = methylglyoxal + NADH + H+
Glossary: methylglyoxal = 2-oxopropanal
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 220.127.116.113, methylglyoxal reductase (NADPH-dependent), in preferring NADH over NADPH as reductant.
