Abstract excerpt
EnvZ is an inner membrane protein present in Escherichia coli that is important for osmosensing and required for porin gene regulation. EnvZ is phosphorylated by intracellular ATP, and EnvZ-P phosphorylates OmpR, which then binds to the porin promoters to regulate their expression. An overexpress...
