Riboviria
Ribozyviria/viroid
image Realm:Duplodnaviria

Viruses in this realm have linear double-stranded DNA genomes and major capsid proteins with HK97-like folds . Their icosahedral capsids (T=3 to T=16 symmetry) have a single vertex portal from which a short or long tail extends.



Class: Herviviricetes PFAM DNA pol B Capping by cellCapsid: HK97-like
Order: Herpesvirales
Class: Caudoviricetes PFAM DNA pol APFAM DNA pol BCapsid: HK97-like
The morphology of viruses is classified according to their tail: Podo-type (short tail), Sipho-type (long tail) or Myo-type (long contractile tail).
