In enzymology, diaminopimelate dehydrogenase (EC 1.4.1.16) is an enzyme that catalyzes the chemical reaction

The three substrates of this enzyme are meso-diaminopimeilic acid, water, and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are (S)-2-amino-6-oxopimelic acid, ammonia, reduced NADPH, and a proton. [1] [2] [3]

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.
