CPS operon
The CPS operon is a regulatory system in ''Escherichia coli'' producing different types of exopolysaccharides (large polysaccharides that are secreted into the environment). Exopolysacharides help protect bacteria from harsh environments, toxic chemicals, and bacteriophages. They serve as matrices to link a number of different bacteria into a community or biofilm. Other bacterial exopolysaccharides cause health problems in humans regulation mechanism of Cps Operon: Reduced levels of MDOs (membrane-derived oligosaccharides) result in autophosphorilation of RcsC. The phosphate group transferred to RcsB. RcsB bind to RcsA. This complex acts on the cps promoter and activates transcription of the cps gene.
