The pCoo plasmid of enterotoxigenic Escherichia coli is a mosaic cointegrate.
CS1 is the prototype of a class of pili of enterotoxigenic Escherichia coli (ETEC) associated with diarrheal disease in humans. The genes encoding this pilus are carried on a large plasmid, pCoo. We report the sequence of the complete 98,396-bp plasmid. Like many other virulence plasmids, pCoo is a mosaic consisting of regions derived from multiple sources. Complete and fragmented insertion seq...
متن کاملSite-directed mutagenesis in Escherichia coli of a stable R772::Ti cointegrate plasmid from Agrobacterium tumefaciens.
The host range of an octopine Ti plasmid is limited to Rhizobiaceae. This has been extended also to Escherichia coli in the form of a stable cointegrate with the wide-host-range plasmid R772. Its structure was studied by constructing a physical map of R772 and of the R772::pTiB6 cointegrate. An insertion sequence present in R772, called IS70, turned out to be involved in cointegrate formation. ...
متن کاملPhysical and functional mapping of two cointegrate plasmids derived from RP4 and TOL plasmid pDK1.
Cointegrate plasmids were formed in vivo between the broad-host-range R-plasmid RP4 and two catabolic plasmids derived from Pseudomonas putida HS1. One of these was the wild-type plasmid pDK1 encoding the complete inducible toluene/xylene (TOL) catabolic pathway and one was pDKT1, a deletion derivative of pDK1 selected after growth of HS1 on benzoate and supporting growth on only toluene. The t...

متن کاملPlasmid-mediated horizontal gene transfer is a coevolutionary process.
Conjugative plasmids are key agents of horizontal gene transfer (HGT) that accelerate bacterial adaptation by vectoring ecologically important traits between strains and species. However, although many conjugative plasmids carry beneficial traits, all plasmids exert physiological costs-of-carriage on bacteria. The existence of conjugative plasmids, therefore, presents a paradox because non-bene...
