Abstract

PEP carboxylase is controlled by phosphorylation in C4 and CAM plants in a unique system in which PEPc kinase is regulated by synthesis/degradation. We have shown the existence of a factor that inhibits or inactivates PEPc kinase, and may play a role in the rapid turnover of this enzyme. We will partially purify this factor, identify its mode of action and investigate how the destruction of PEPc kinase is regulated. We have also developed an assay for PEPc kinase translatable mRNA. We will use this assay to investigate the signalling systems that control the expression of PEPc kinase, paying close attention to the possible role of metabolite control of expression.
