Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalytic activityi

3-phospho-D-glycerate + NAD+ = 3-phosphonooxypyruvate + NADH.
2-hydroxyglutarate + NAD+ = 2-oxoglutarate + NADH.

Enzyme regulationi

In bacteria displays feedback inhibition by L-serine.

Pathwayi: L-serine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-serine from 3-phospho-D-glycerate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. D-3-phosphoglycerate dehydrogenase (serA)
  2. Phosphoserine aminotransferase (serC)
  3. Phosphoserine phosphatase (serB)
This subpathway is part of the pathway L-serine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-serine from 3-phospho-D-glycerate, the pathway L-serine biosynthesis and in Amino-acid biosynthesis.

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.
