Table S1.
Average number of FSF domains in each phyla/kingdom corresponding to the seven general functional categories. Numbers were rounded up when the decimal value exceeded 0.5 and rounded down otherwise. Nanoarchaeota and Tenericutes have the least number of metabolic domains and are highlighted in bold. Eukaryal kingdoms (Fungi, Metazoa, Plants and Protista) have the richest FSF repertoires compared to the prokaryotes.
