Viral metagenome translated BLAST homologs sorted according to annotated functional gene category. Each sequence was assigned to a presumptive functional category based on the highest-quality sequence homolog. The most likely phylogenetic affiliations (virus, bacteria, prophage, and mobile element) for each sequence category are indicated. Asterisks indicate categories that could not contain prokaryote sequences because they are purely viral functions.
