Gene

Organism
Corynebacterium glutamicum (strain ATCC 13032 / DSM 20300 / JCM 1318 / LMG 3730 / NCIMB 10025)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the reversible NADPH-dependent reductive amination of L-2-amino-6-oxopimelate, the acyclic form of L-tetrahydrodipicolinate, to generate the meso compound, D,L-2,6-diaminopimelate. Probably plays a role in lysine biosynthesis. Exhibits a high substrate specificity for meso-2,6-diaminopimelate, since L,L-2,6-diaminopimelate, D,D-2,6-diaminopimelate, L-glutamate, L-alanine, L-leucine, L-valine, L-aspartate, L-threonine, L-homoserine, L-methionine, L-lysine, L-serine, L-phenylalanine, L-tyrosine, L-tryptophan, L-ornithine, L-histidine, L-arginine, D-glutamate, and D-alanine are not substrates for the oxidative deamination reaction. Can use NAD+ only poorly since the activity observed in the presence of NAD+ is about 3% of that with NADP+.2 Publications

Catalytic activityi

Meso-2,6-diaminoheptanedioate + H2O + NADP+ = L-2-amino-6-oxoheptanedioate + NH3 + NADPH.2 Publications

Enzyme regulationi

L,L-2,6-diaminopimelate and D,D-2,6-diaminopimelate competitively inhibit the oxidative deamination of meso-2,6-diaminopimelate. The enzyme is also inhibited by L-cysteine, and by p-chloromercuribenzoate, iodoacetic acid and HgCl2 in vitro.1 Publication

Kineticsi

  2. KM=0.12 mM for NADP+1 Publication
  3. KM=0.13 mM for NADPH1 Publication
  4. KM=0.28 mM for L-2-amino-6-oxoheptanedioate1 Publication
  5. KM=36 mM for ammonia1 Publication

    pH dependencei

    Optimum pH is about 9.8 for the oxidative deamination of meso-diaminopimelate and 7.9 for the reductive amination of L-2-amino-6-oxopimelate.1 Publication

    Pathwayi: L-lysine biosynthesis via DAP pathway

    This protein is involved in step 1 of the subpathway that synthesizes DL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate.
    Proteins known to be involved in this subpathway in this organism are:
    1. Meso-diaminopimelate D-dehydrogenase (ddh)
    This subpathway is part of the pathway L-lysine biosynthesis via DAP pathway, which is itself part of Amino-acid biosynthesis.
