  • a All of the archaeal and eukaryotic genomes analyzed belong to separate genera. However, the bacterial genomes analyzed encompass 136 different species that belong to 89 genera.

  • b Of the 174 bacterial genomes analyzed, 60 of the strains belong to 22 different bacterial species. Of these, 51 strains that belong to 18 different bacterial species encode PTS protein homologues.

  • c Only completely sequenced genomes were analyzed. Incompletely sequenced genomes (e.g., sequenced without closure) were not included in the present analyses.
