The 3 substrates of this enzyme are meso-2,6-diaminoheptanedioate, H2O, and NADP+, whereas its 4 products are L-2-amino-6-oxoheptanedioate, NH3, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is meso-2,6-diaminoheptanedioate:NADP+ oxidoreductase (deaminating). Other names in common use include meso-alpha,epsilon-diaminopimelate dehydrogenase, and meso-diaminopimelate dehydrogenase. This enzyme participates in lysine biosynthesis.
Structural studies
As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1DAP, 1F06, 2DAP, and 3DAP.
