pAD1 is a 59.3-kb plasmid in Enterococcus faecalis that has been the subject of intense investigation with regard to its pheromone-inducible conjugation behavior as well as its contribution to virulence. Approximately two-thirds of the pAD1 nucleotide sequence has been previously reported. Here we report on an analysis of the final similar to 22 kb, a significant portion of which is believed to ...
Zusammenfassung
pAD1 is a 59.3-kb plasmid in Enterococcus faecalis that has been the subject of intense investigation with regard to its pheromone-inducible conjugation behavior as well as its contribution to virulence. Approximately two-thirds of the pAD1 nucleotide sequence has been previously reported. Here we report on an analysis of the final similar to 22 kb, a significant portion of which is believed to encode structural genes associated with conjugation. The conjugation-regulated region was also found to contain a new (second) origin of conjugative transfer (oriT). A list of open reading frames covering the entire plasmid is presented.
