Comparison of plasmids Co1E2-P9 and Co1E2-CA42 and their immunity proteins.
Plasmids ColE2-CA42 (6.1 kilobases) and ColE2-P9 (6.8 kilobases) were found to have homologous (4.3-kilobase) DNA segments which contain their colicin and immunity genes. The relatedness of their immunity proteins was verified by determining their amino acid compositions and N-terminal sequences. These characteristics were compared with those of ColE3-CA38.
