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, L-lactate dehydrogenase (LDHAL6A), L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase (LDHC), L-lactate dehydrogenase (LDHC), L-lactate dehydrogenase (LDHC), L-lactate dehydrogenase, L-lactate dehydrogenase (LDHC), L-lactate dehydrogenase, L-lactate dehydrogenase B chain (LDHB), L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase (EGM_05803), L-lactate dehydrogenase, L-lactate dehydrogenase, L-lactate dehydrogenase (EGM_05805), L-lactate dehydrogenase A-like 6B (LDHAL6B), L-lactate dehydrogenase, L-lactate dehydrogenase A chain (LDHA), L-lactate dehydrogenase, L-lactate dehydrogenase (EGM_17551), L-lactate dehydrogenase
This subpathway is part of the pathway pyruvate fermentation to lactate, which is itself part of Fermentation.
