In Escherichia coli, OmpR and EnvZ comprise a two component regulatory system that controls the relative expression of the outer membrane porin proteins, OmpF and OmpC. In this system, OmpR functions as a transcriptional regulator, serving as an activator of ompC, and as both an activator and a repressor of ompF. Previous evidence suggests that OmpR… CONTINUE READING
