FIG. 5.

Comparison of the boundaries between the 3′-CS and tni regions of In31 and In5. The 3′-CS sequences are represented in boldface type. In In31 the 3′-CS merges directly with the truncated tniBΔ2 gene, while in In5 IS1326 is inserted between the 3′-CS boundary and tniBΔ2. A 2-bp deletion is also present at the 3′-CS boundary of In31 compared with that of In5 (5).
