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 B chain (LDHB), L-lactate dehydrogenase A chain (LDHA)
This subpathway is part of the pathway pyruvate fermentation to lactate, which is itself part of Fermentation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-lactate from pyruvate, the pathway pyruvate fermentation to lactate and in Fermentation.
