In vivo phosphorylation of PEPC in Egeria densa was studied using plants at high temperature and in light, and plants kept at low temperature and in light. The isoform induced by high temperature and light was more phosphorylated in the light. Changes in kinetic and regulatory properties correlated with changes in the phosphorylation state of PEPC.

Keywords: Key words: Egeria densa — Phosphoenolpyruvate carboxylase — Phosphorylation.; Abbreviations: CAM, crassulacean acid metabolism; PEP, phosphoenolpyruvate; PEPC, phosphoenolpyruvate carboxylase; PPDF, photosynthetic photon density fluence; SDS-PAGE, sodium dodecyl sulfate–polyacrylamide gel electrophoresis.
