  1. Selenoproteins are found in a variety of phyla within all three lines of descent of life. The number of genomes encoding selenoproteins is indicated ('selenogenomes') together with the total number of sequenced genomes in the phylum. Numbers are based on data obtained in [8] except that any completed genomes entered into GenBank since 31 December 2003 were added to the total genome number and those possessing both selB and selD homologs were added to the number of selenoprotein-encoding genomes.
