FIG. 1.

Structural organization of the 9,610-bp plasmid pPCP1 derived from Y. pestis KIM5. BLAST searches using the entire nucleotide sequence obtained in this work were performed to precisely localize potential new ORFs, insertion sequence elements, and the three previously described genes present in pPCP. The directions of transcription of these genes are indicated by the arrows. The single IS100 element was used to define position 1 of this plasmid. The characteristics of the genes and proteins involved are described in the text. The numbering above the line is the molecular size in base pairs.
