FIG. 2.

(A) Schematic representation of H. pylori fliP and positions of the poly(C) repeat (arrow) and insertion points of the kanamycin resistance cassette in plasmids pCJ55 (triangle; insertion into EcoRI site) and pCJ57 (trapezoid; 50-bp deletion). (B) Nucleotide sequences and deduced translation (in three-letter code) of the region surrounding the poly(C) repeat in a motile and a nonmotile variant of H. pylori 26695, in the nonmotile strain Tx30a, and in H. pylori N6. The repeat is located 315 nucleotides downstream of the fliP start codon.
