    Pathwayi: L-serine biosynthesis

    This protein is involved in step 3 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. no protein annotated in this organism
    3. Phosphoserine phosphatase (MJ1594)
    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.
