Light modulation of phosphofructokinase in pea leaf chloroplasts.
Chloroplastic phosphofructokinase, phosphorylase, phosphoglucomutase, and phosphoglucoisomerase in peas are light inactivated. The effect of light on phosphofructokinase is mimicked by dithiothreitol. DCMU, arsenite, and sulfite inhibit light modulation of the enzyme. No effect of light inactivation on the K(m) (fructose-6-P) or pH optima of phosphofructokinase was observed.
