In vivo phosphorylation of phosphoenolpyruvate carboxylase in Egeria densa, a submersed aquatic species.
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.
