Molecular Model of Osmoregulatory switch operative at Low Osmolarity in Escherichia coli. The low osmolarity conditions favour the phosphatase activity of EnvZ. The Phosphatase domain (EnvZp) upon autophosphorylation leads to formation of EnvZppOmpR complex and later favours the dephosphorylation of the cellular OmpRP thus making OmpRP available only for cooperative binding to the high affinity promoter of OmpF namely F1, F1F2, and F1F2F3 favouring OmpF expression.
