In enzymology, a N5-(carboxyethyl)ornithine synthase (EC 1.5.1.24) is an enzyme that catalyzes the chemical reaction
- N5-(L-1-carboxyethyl)-L-ornithine + NADP+ + H2O L-ornithine + pyruvate + NADPH + H+
The 3 substrates of this enzyme are N5-(L-1-carboxyethyl)-L-ornithine, NADP+, and H2O, whereas its 4 products are L-ornithine, pyruvate, NADPH, and H+.
Nomenclature
[edit]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 N5-(L-1-carboxyethyl)-L-ornithine:NADP+ oxidoreductase (L-ornithine-forming). Other names in common use include 5-N-(L-1-carboxyethyl)-L-ornithine:NADP+ oxidoreductase, and (L-ornithine-forming).
