FIG 2.

The chemoreceptor repertoires of H. pylori and C. jejuni. Receptor topology and locus tags of H. pylori 26695 and C. jejuni subsp. jejuni NCTC 11168 are shown. Pfam names for all LBDs are shown, except for 4HB, which is predicted to be a divergent four-helix bundle domain. Domains that are not detected by the Pfam tool HMMER but are recognized by the more sensitive HHpred tool are indicated as empty rectangles. Orthologous groups of chemoreceptors (including paralogs) are highlighted by blue shading.
