Protein

LL-diaminopimelate aminotransferase

Gene

dapL

Organism
Prochlorococcus marinus (strain NATL2A)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Involved in the synthesis of meso-diaminopimelate (m-DAP or DL-DAP), required for both lysine and peptidoglycan biosynthesis. Catalyzes the direct conversion of tetrahydrodipicolinate to LL-diaminopimelate.UniRule annotation

Catalytic activityi

LL-2,6-diaminoheptanedioate + 2-oxoglutarate = (S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate + L-glutamate + H2O.UniRule annotation

Cofactori

pyridoxal 5'-phosphateUniRule annotation

Pathwayi: L-lysine biosynthesis via DAP pathway

This protein is involved in step 1 of the subpathway that synthesizes LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate (aminotransferase route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. LL-diaminopimelate aminotransferase (dapL)
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 LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate (aminotransferase route), the pathway L-lysine biosynthesis via DAP pathway and in Amino-acid biosynthesis.
