ColA is a colicinogenic plasmid of 6.72 kb. It is compatible with ColE1 but not with ColK. Transposon insertion mutagenesis as well as complementation studies have been carried out to investigate the location of the various functional regions of this plasmid. Four independent ColA::Tn1 and one ColA::Tn3 plasmids were isolated and the locations of insertions were determined. From these plasmids, six different deletion mutants were constructed. In addition, various restriction fragments of ColA have been cloned into pUC8 to carry out complementation studies. We have thus confirmed the location of the DNA regions involved in colicin production, colicin release and immunity function. The DNA region involved in conjugal mobility promoted by R64 drd11 has been identified and we have demonstrated that the ColE1 mobility proteins can act in trans on the bom (basis of mobility) site of ColA. The location of this site, as well as the region involved in stable maintenance of ColA, have also been determined. These results are discussed with regard to the homology in nucleotide sequence between ColA and ColE1.
