Control of the phosphorylation of phosphoenolpyruvate carboxylase in higher plants

Phosphoenolpyruvate (PEP) carboxylase is regulated by reversible phosphorylation in higher plants. Recently several genes encoding PEP carboxylase kinase have been cloned. The purpose of this article is to assess the contribution that information on the structure and expression of these genes is making to our understanding of the posttranslational control of PEP carboxylase activity.
