| nucleotide sequences from the colicin e5, e6 and e9 operons: presence of a degenerate transposon-like structure in the cole9-j plasmid. | the nucleotide sequences of 1288 bp of plasmid cole5-099, 1609 bp of cole6-ct14 and 2099 bp of cole9-j were determined. these sequences encompass the structural genes for the c-terminal receptor-binding and nuclease domains of colicins e5, e6 and e9, their cis- or trans-acting immunity proteins and four lysis proteins including an atypical one of non-lipoprotein nature (lys) present in the cole9-j plasmid. the cole6 gene organisation, in the order col-imm-e8imm-lys, is identical to that found in ... | 1989 | 2549375 |
