In enzymology, a D-nopaline dehydrogenase (EC 1.5.1.19) is an enzyme that catalyzes the chemical reaction

N2-(D-1,3-dicarboxypropyl)-L-arginine + NADP+ + H2O L-arginine + 2-oxoglutarate + NADPH + H+

The 3 substrates of this enzyme are N2-(D-1,3-dicarboxypropyl)-L-arginine, NADP+, and H2O, whereas its 4 products are L-arginine, 2-oxoglutarate, NADPH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is N2-(D-1,3-dicarboxypropyl)-L-arginine:NADP+ oxidoreductase (L-arginine-forming). Other names in common use include D-nopaline synthase, nopaline dehydrogenase, nopaline synthase, NOS, 2-N-(D-1,3-dicarboxypropyl)-L-arginine:NADP+ oxidoreductase, and (L-arginine-forming). This enzyme participates in arginine and proline metabolism.

Opines are low molecular weight compounds found in plant crown gall tumors or hairy root tumors produced by pathogenic bacteria of the genus Agrobacterium and Rhizobium. Opine biosynthesis is catalyzed by specific enzymes encoded by genes contained in a small segment of DNA, which is part of the Ti plasmid or Ri plasmid, inserted by the bacterium into the plant genome. The opines are used by the bacterium as an important energy, carbon and nitrogen source. Each strain of Agrobacterium and Rhizobium induces and catabolizes a specific set of opines, this set typifying the Ti plasmid and Ri plasmid. There are some 30 different opines described so far.

In enzymology, an aspartate-semialdehyde dehydrogenase is an enzyme that is very important in the biosynthesis of amino acids in prokaryotes, fungi, and some higher plants. It forms an early branch point in the metabolic pathway forming lysine, methionine, leucine and isoleucine from aspartate. This pathway also produces diaminopimelate which plays an essential role in bacterial cell wall formation. There is particular interest in ASADH as disabling this enzyme proves fatal to the organism giving rise to the possibility of a new class of antibiotics, fungicides, and herbicides aimed at inhibiting it.
