Relatedness of core proteins predicted to be encoded by H. pylori strains 98-10 and 26695. A set of 1237 genes present in all 5 H. pylori strains was identified, as described in the Methods. The deduced amino acid sequences of the corresponding proteins encoded by strain 98-10 were used to search a database of sequences from strain 26695 using FastA. The best match was identified, and the percent amino acid identity was calculated. The histogram shows the number of ORFs exhibiting the indicated level of amino acid identity.
