Figure 3. Schematic representation of cysteine and methionine metabolism (based on KEGG pathway 00270).

Figure 3

In blue, reactions predicted in H. cetorum but not H. pylori with locus tags of the unique H. cetorum rhodanese-related sulfurtransferase gene indicated. In red, reactions predicted in H. pylori but not H. cetorum. In black, reactions predicted in both H. cetorum and H. pylori. A reaction for which no predicted enzymes were found in Helicobacter genomes is indicated by the dotted line and arrowheads in gray. Of note, DNA sequences matching those of HP1045 (acetyl CoA synthetase) are missing by BLASTN criteria from each H. cetorum strain, and also from 14 of the 48 fully sequenced H. pylori genomes screened. HP1045 was not included in Table 5 because of its absence from a significant minority of H. pylori strains.
