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.
