Berrylium Fluoride activated receiver domain of E.coli PhoP
Overview
The response regulator PhoP is part of the PhoQ/PhoP two-component system, involved in responses to depletion of extracellular Mg(2+). Here, we, report the crystal structures of the receiver domain of Escherichia coli, PhoP determined in the absence and presence of the phosphoryl analog, beryllofluoride. In the presence of beryllofluoride, the active receiver, domain forms a twofold symmetric dimer similar to that seen in structures, of other regulatory domains from the OmpR/PhoB family, providing further, evidence that members of this family utilize a common mode of dimerization, in the active state. In the absence of activating agents, the PhoP, receiver domain crystallizes with a similar structure, consistent with the, previous observation that high concentrations can promote an active state, of PhoP independent of phosphorylation.
