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 B-A chain (ldhba), L-lactate dehydrogenase (ldhbb), L-lactate dehydrogenase A chain (ldha), L-lactate dehydrogenase (ldhbb), L-lactate dehydrogenase B-B chain (ldhbb)
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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
