The immunity genes of colicins E2 and E8 are closely related.
We have determined the nucleotide sequence of the newly characterized colicin E8 imm gene which exists in tandem with the colicin E3 imm gene in the ColE3-CA38 plasmid. Comparison of these immunity structures reveals considerable sequence divergence, but the ColE8 imm gene is markedly homologous to the colicin E2 imm gene from the ColE2-P9 plasmid.
