WebAug 10, 2011 · PhoQ/PhoP is a two-component system (TCS) that governs virulence, monitors extracellular Mg 2+, and regulates several cellular activities in many gram-negative species [4]. The PhoQ/PhoP TCS consists of the transmembrane sensor PhoQ and the cytoplasmic regulator PhoP. Webthe membrane-bound sensor proteins, whereas PhoP is a member of the DNA-binding OmpR family. Deletion mutants lacking phoP or phoR-phoP, were unable to grow in minimal medium at low phosphate concentration (10 M). Growth was fully restored by complementation with the phoR-phoP genes. Both S. lividans phoP and phoR-phoP …
