Abstract
ADP was found to inhibit the activity of nitrate reductase from tomato leaves in vitro. No effects of ATP, AMP, adenosine and adenine could be detected. Orthophosphate promoted activity only in the presence of high concentrations of NADH2.It is suggested that nitrate reductase possesses characteristics of a regulatory enzyme and that ADP brings about a transformation in the conformation of the enzyme, with a resulting decrease in its activity.
