Figure 1. Schematic comparison of CTn5 and the homologous element present in strain 2007855. Blue ORFs have homologs present in CTn5, green ORFs are not present in CTn5, pink ORFs are interrupted by insertion of new sequence compared with CTn5. Regions of homology are indicated by colored boxes: the red box shows the recombination module, the blue box shows the accessory module, the brown boxes show the conjugation module.
