[Malic acid induction of decarboxylating NADP-malate dehydrogenase synthesis in C3-plant leaves].
The activity of decarboxylating NADP-malatedehydrogenase (E. C. 1.1.1.40) in green ethiolated pea and barley leaves and in green leaves of a pea mutant lacking photosystem II is found to be 3-fold increased after the injection of malic acid into cut plants. Protein synthesis inhibitors depressed malic acid-induced increase of the activity of "malic"-enzyme, the effect of chloramphenicol being more pronounced in ethiolated green leaves, and that of cycloheximide--in leaves of a mutant with formed photosynthetic apparatus. Possible dependence of malate-induced biosynthesis of "malic"-enzyme on the degree of NADP reduction in chloroplasts is discussed.
