Cbi is the [[Colicin Immunity Protein]] produced by ''E. coli'' alongside [[Colicin B]] to protect itself from the cytotoxic pore-forming domain of the [[Colicin]]. Once the complex has been released and bound to an outer membrane receptor of the target cell, the immunity protein is released.
Cbi is the [[Colicin Immunity Protein]] produced by ''E. coli'' alongside [[Colicin B]] to protect itself from the cytotoxic pore-forming domain of the [[Colicin]], by inserting itself into the cell membrane and preventing the colicin from doing the same. This prevents membrane depolarisation by the colicin, so the cell is not killed.
