Figure 4

Genetic map of the dnd- encoding genomic islands of E . coli KTE9 and KOEGE118 which harboured 2 copies of dnd operons. The integrase gene is the first element of the dnd-encoding genomic island (GI) although the genetic map is illustrated according to the orientation of the dnd operons to facilitate visualization. Same-strand DNA similarity is shaded blue (dark blue-sky blue) while reverse similarity is shaded red (red-light pink). Coding sequences are displayed as arrows. Major features are displayed and are colored to facilitate visualization. Red alphabet in brackets indicates the subgroup determined based on the immediate genetic environment of the respective dnd operons. An additional DNA segment of 74 kb was observed for dndI_IIEC KOEGE 118 compared to dndI_IIEC KTE 9. dndI_IEC KOEGE 118 is identical to dndI_IEC KTE 9.
