Schematic representation of the alignment of plasmids pVAS24-VEB, pVPS72-VEB, and pMS260 with similar IncQ plasmid backbones. The two red rectangles surrounding IS186 denote the left and right inverted repeats. The 13-bp segment is the target site duplication upon the insertion of IS186. Red arrows indicate the resistance genes, and blue arrows stand for maintenance genes in plasmids. The gray scale at the bottom right depicts percentages of sequence homology.
