Figure 4. Genetic structure of penicillinase plasmid pPM1 and its segregant.

Figure 4

In A, pPM1 structure is shown. Inner circle indicates homologous regions to S. aureus plasmid SAP014A (GenBank accession number GQ900379), SAP063A (GenBank accession number GQ900418), and pSK156 (GenBank accession number GQ900448). The IS431 region with the transposase gene (tnp) is shaded in light green. A Greek delta symbol indicates truncated coding sequence. In B, a segregant of pPM1 in MEStet locus is shown. Tetr, tetracycline-resistant; Tets, tetracycline-susceptible.
