EnvZ is a sensory histidine kinase in Escherichia coli to regulate the phosphorylation of OmpR, its cognate response regulator, required for the expression of genes for outer membrane porin proteins. Here, we re-examined the recent paper Mattison and Kenney, in which the authors reported that phosphorylated OmpR (OmpR-P) is unable to bind to EnvZ, thus casting doubts on the role of the EnvZ phosphatase activity in vivo. Using an identical method, the Kd value for the interaction of the… CONTINUE READING
