Abstract
Calcium-dependent phosphoenolpyruvate carboxylase protein kinase was c opurified with C-4 phosphoenolpyruvate carboxylase (C-4 PEPC) from ill uminated Sorghum leaves during purification by various procedures. Iso lated 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.
