Protein

Diaminopimelate epimerase

Gene

dapF

Organism
Prochlorococcus marinus (strain NATL2A)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L-lysine and an essential component of the bacterial peptidoglycan.UniRule annotation

Catalytic activityi

LL-2,6-diaminoheptanedioate = meso-diaminoheptanedioate.UniRule annotation

Pathwayi: L-lysine biosynthesis via DAP pathway

This protein is involved in step 1 of the subpathway that synthesizes DL-2,6-diaminopimelate from LL-2,6-diaminopimelate.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Diaminopimelate epimerase (dapF)
This subpathway is part of the pathway L-lysine biosynthesis via DAP pathway, 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 DL-2,6-diaminopimelate from LL-2,6-diaminopimelate, the pathway L-lysine biosynthesis via DAP pathway 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.
