IUBMB Enzyme Nomenclature


Accepted name: L-lactate dehydrogenase

Reaction: (S)-lactate + NAD+ = pyruvate + NADH + H+

Other name(s): lactic acid dehydrogenase; L(+)-nLDH; L-(+)-lactate dehydrogenase; L-lactic dehydrogenase; L-lactic acid dehydrogenase; lactate dehydrogenase; lactate dehydrogenase NAD-dependent; lactic dehydrogenase; NAD-lactate dehydrogenase

Systematic name: (S)-lactate:NAD+ oxidoreductase

Comments: Also oxidizes other (S)-2-hydroxymonocarboxylic acids. NADP+ also acts, more slowly, with the animal, but not the bacterial, enzyme.
