WebJan 1, 2013 · PhoR autophosphorylates and modulates the phosphorylation of PhoB with its phosphotransferase and phosphatase activities. Phosphorylated PhoB binds to the pho box and activates the transcription of phoBphoR. ( B) Time-dependent expression of PhoB upon phosphate starvation. WebThe phospho-PhoB is then capable of activating expression of the Pho regulon genes, two of the examples are phoA and phoBR. In high phosphate concentration, phoR is turned into an inhibitory state, which interferes with phosphorylation of PhoB. PhoB is, thus, not capable of activating expression of phoA and phoBR. Design
