CoIV plasmids pCoIV-B188 and pCoIV-K30: genetic maps according to restriction enzyme sites and landmark phenotypic characteristics.
The CoIV plasmids are large virulence plasmids of the incompatibility group IncFI. We have obtained the genetic maps of two of the most studied CoIV plasmids, pCoIV-B188 and pCoIV-K30, according to restriction enzyme sites and landmark phenotypic characteristics such as colicin V, the aerobactin iron uptake system, the transfer region, replication regions, and repeated sequences. Although the two plasmids differ in size (pCoIV-B188 is 80 kb and pCoIV-K30 is 144 kb), the maps reveal many regions which are apparently identical or very similar.
