Adnaviria
Viruses from this realm are archaeal filamentous viruses with linear A-form double-stranded DNA genomes
and characteristic major capsid proteins with SIRV2-like folding, which have nothing to do with those of other known viruses .
The realm is called Adnaviria, which refers to the double-helical structures of the A-form that have been adapted from the viral genomes in the nucleocapsids.
