Functioni

Catalytic activityi

(S)-lactate + NAD+ = pyruvate + NADH.

Pathwayi: pyruvate fermentation to lactate

This protein is involved in step 1 of the subpathway that synthesizes (S)-lactate from pyruvate.
Proteins known to be involved in this subpathway in this organism are:
  1. L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase (Ldhb), L-lactate dehydrogenase (Ldhc), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase B chain (Ldhb), L-lactate dehydrogenase (Ldhc), L-lactate dehydrogenase (Ldhal6b), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase A chain (Ldha), L-lactate dehydrogenase (Ldhb), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase (Ldhc), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase (Ldha), L-lactate dehydrogenase C chain (Ldhc), L-lactate dehydrogenase (Ldhc)
This subpathway is part of the pathway pyruvate fermentation to lactate, which is itself part of Fermentation.
