In enzymology, N5-(carboxyethyl)ornithine synthase (EC 1.5.1.24) is an enzyme that catalyzes the chemical reaction

N(5)-(L-1-carboxyethyl)-L-ornithine
 
 
H2O
H+
H2O
H+
 
+ NADPH +
 

The three substrates of this enzyme are N5-(L-1-carboxyethyl)-L-ornithine, oxidised nicotinamide adenine dinucleotide phosphate (NADP+), and water. Its products are L-ornithine, reduced NADPH, pyruvic acid, and a proton.[1][2]

Nomenclature

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).
