View source for ImmE6

ImmE6 is an immunity protein produced by ''E. coli'' to protect itself from [[Colicin E6]] and its cytotoxic [[16s rRNase activity]], by binding to the enzymatic C domain and repressing its activity. This occurs to prevent the colicin from killing the cell it is produced in. It is then released when ColE6 binds to [[BtuB]], the outer membrane receptor on the target cell.
