Promoter OmpF is activated by phosphorylated OmpR at low osmolarity, and is repressesed by phosphorylated OmpR at high osmolarity.In Escherichia coli, osmoregulation is mediated in part by the actions of such a two-component system consisting of EnvZ and OmpR. These proteins
act to control the relative levels of the outer membrane porin genes, ompF and ompC. At low osmo larity, OmpF predominates in the outer membrane, while at high osmolarity the OmpF porin is replaced by OmpC.OmpF has a larger pore and a faster ??ow rate than OmpC.
