Protein

Diaminopimelate epimerase

Gene

dapF

Organism
Yersinia pestis
Status
Reviewed-Annotation score: -Protein inferred from homologyi

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), 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.
