Abstract excerpt
In Escherichia coli, expression of the outer membrane proteins, OmpF and OmpC, is regulated by the regulatory factors, EnvZ and OmpR, at the transcriptional level in response to the medium osmolarity. In this particular osmotic regulation, phosphorylation of OmpR at an aspartate residue (Asp-55)...
