pMW2-like plasmids with full-length Tn552. (A) Diagram of the pMW2 sequence positions 2407–12018, including the complete Tn552 with flanking 10 bp direct repeats (gray arrowheads). All pMW2-like plasmids (Table 7) have a frameshift that truncates the p480 transposase and generates a second putative ORF. pMW2 and the four plasmids listed have a 75 bp deletion in sin; the four remaining pMW2-like plasmids have the full sin gene. (B) The pMW2 sequence that flanks Tn552, positions 4831–11469. Tn552 (6553 bp, including the 10 bp DR) is inserted into the putative sin res site; res siteI and res siteII predicted for p21 (Rowland et al. 2002) are labeled (black arrows). This sequence is identical in all pMW2-like plasmids. The gray arrows show the 10 bp direct repeats.
