Phosphorelay system
WebThe Rcs phosphorelay pathway in Escherichia coli is a response system that senses outer membrane stress conditions and regulating capsule and biofilm formation which can result in antibiotic resistance. The Rcs phosphorelay system consists of the outer membrane sensor protein RcsF, a sensor kinase RcsC, a response WebIn addition, the BarA/UvrY and Rcs phosphorelay systems can activate rpoS transcription and translation respectively. These systems are involved in the control of motility, biofilm …
