Phosphoenolpyruvate carboxylase (PEPC) was characterized in extracts from C4 mesophyll protoplasts isolated from Digitaria sanguinalis leaves and shown to display the structural, functional, and regulatory properties typical of a C4 PEPC. In situ increases in the apparent phosphorylation state of the enzyme and the activity of its Ca2+-independent protein-serine kinase were induced by light plus NH4Cl or methylamine. The photosynthesis-related metabolite 3-phosphoglycerate (3-PGA) was used as a… CONTINUE READING
