Reaction

Reaction Comment Organism Reaction ID
N2-(D-1-carboxyethyl)-L-arginine + NAD+ + H2O = L-arginine + pyruvate + NADH + H+ partially ordered mechanism. NADPH binds first followed by the random order, rapid-equilibrium-binding of Arg and pyruvate. Orn probably binds before pyruvate Helianthus annuus
