WebFeb 9, 2024 · The sensor protein PhoQ functions as a phosphatase that dephosphorylates the cognate response regulatory protein PhoP . Thus, defect in the phoQ gene results in constitutive expression of the PhoP regulated genes . PhoP directly binds to the promoter region of the oprH-phoP-phoQ operon and activates its transcription . WebApr 13, 2024 · HmsB, a temperature-dependent sRNA, promotes biofilm formation by Yersinia pestis, but whether its own expression is regulated by other regulators is still poorly understood. RovM is a global regulator that activates biofilm formation but represses the virulence of Y. pestis. In this work, the results of primer extension, quantitative real-time …
