The distribution of pathways in MetaCyc based on the taxonomic classification of associated species

Bacteria Eukarya Archaea
Proteobacteria 1042 Viridiplantae 916 Euryarchaeota 137
Firmicutes 319 Fungi 343 Crenarchaeota 42
Actinobacteria 280 Metazoa 312 Thaumarchaeota 1
Bacteroidetes/Chlorobi 62 Euglenozoa 28
Cyanobacteria 65 Alveolata 16
Deinococcus-Thermus 28 Amoebozoa 10
Tenericutes 18 Stramenopiles 7
Thermotogae 25 Fornicata 4
Aquificae 16 Rhodophyta 4
Spirochaetes 12 Haptophyceae 4
Chlamydiae -Verrucomicrobia 7 Parabasalia 3
Planctomycetes 6
Chloroflexi 5
Fusobacteria 4
Nitrospirae 2
Thermodesulfobacteria 2
Chrysiogenetes 1

For example, the statement ‘Tenericutes 18’ means that there is experimental evidence for at least 18 MetaCyc pathways for their occurrence in members of this taxonomic group. Major Taxonomic groups are grouped by domain and are ordered within each domain based on the number of pathways (number following taxon name) associated with the taxon. A pathway may be associated with multiple organisms.
