FIG. 1.

Linear representation of the H. pylori J99 chromosome, illustrating the location of each predicted protein-coding region, rRNA gene, tRNA gene, IS605 or IS606 element and related fragment, and NotI endonuclease site. The predicted protein-coding regions are color coded based on functional classification (see the bottom of the figure for the code), with the direction of transcription indicated by an arrowhead. H. pylori J99 ORFs are numbered sequentially in red, and the corresponding homologous gene, if it exists in strain 26695, is numbered in black. The positions of the NotI endonuclease sites in J99 are indicated with the number of conserved nucleotides in the recognition sequence (x/8) at the corresponding position in strain 26695. The numbers associated with the tRNA symbols (inverted triangles) represent the number of tRNA genes at a specific locus. Vertical hash marks, below the linear chromosome, are located every 20 kb.
