FIG. 2.
A schematic map of a 5.5-kb EcoRI-SphI fragment of pS12 surrounding blaCTX-M-14. An arrow indicates the position and orientation of each open reading frame (Orf) or putative gene presumed by its homology. The line bar in the upper part indicates the location of each insertion sequence. Shown in the lower part are schematic maps containing regions of the plasmids and transposon homologous to the segments (A to E) of the 5.5-kb fragment of pS12. Names are indicated on the left. Putative products of Orfs are indicated in parentheses. Black bars indicate the locations of sequences homologous to those of the corresponding regions of pS12. tnpA, sequence encoding the transposase of each insertion sequence. -35 and -10 represent -35 and -10 sequences of the ISEcp1B-mediated promoter. d-iron, truncated gene encoding a putative outer membrane protein for iron transport.
