摘要：

Calcium-dependent phosphoenolpyruvate carboxylase protein kinase was copurified with C-4 phosphoenolpyruvate carboxylase (C-4 PEPC) from illuminated Sorghum leaves during purification by various procedures. Isolated mesophyll cell protoplasts contained both calcium-dependent and -independent protein kinases. The latter was induced by light and weak bases and was found to be the major protein kinase phosphorylating C-4 PEPC in the mesophyll.
