FIG. 1.
Schematic map of a 9,590-bp DNA fragment of the natural plasmid pILT-3 from K. pneumoniae ILT-3 containing ISEcp1B, IS903D, and the blaCTX-M-19 gene. The 5′ and 3′ conserved sequences (5′-CS and 3′-CS) of class 1 integrons are indicated in the upper left part of the figure. ORFs and genes are shown as boxes with an arrow indicating the transcription orientation. Black dots are for 59-be sequences. IRL and IRR motifs are indicated by vertical arrows. The IRL and IRR of the ISEcp1B-mobilized DNA fragment are boxed, those of the ISEcp1B element are italicized, and those of IS903D are in lowercase; the inverted repeat left of Tn1721 (Irl) is also shown. The cloned sequences of recombinant plasmids are indicated by arrows at both ends, with the corresponding plasmid names indicated on the right.
