Protein
Diaminopimelate epimerase
Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Function
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 (PubMed:10194362, PubMed:16723397). Only accepts DAP isomers with the L configuration (PubMed:16723397).
Similarity
Belongs to the diaminopimelate epimerase family.
