Integrons in SGI1 and SGI2. (A) SGI1 is a 42.4-kb mobilizable integrated element. The map of SGI1 was generated from the sequence under GenBank accession no. AF261825. (B) Complete sequence of the integron in SGI2 and its immediate surrounds (this study) (GenBank accession no. AY963803). The surrounding SGI1 backbone and the adjacent chromosomal region are shown below the integron. Narrow vertical bars represent the inverted repeats (IRi and IRt) of class 1 integrons, and the 5′-CS, 3′-CS, and tni regions are indicated by lines of different thicknesses. The attI1 site is shown as a tall open box, and gene cassettes are shown as open boxes with a black bar at one end, indicating the attC sites (59-be). IS6100 and the central, non-integron-derived region are shown as open boxes. Arrows indicate the position and orientation of genes and open reading frames, which are named or numbered.
