Scientific name

Bamfordvirae

Short name

DJRV

Bamfordvirae refers to a realm of viruses . This taxon is characterized by Hauptkapsidproteine ( English major capsid protein ) with " double jelly roll " structure ( DJR viruses ). Prior to official confirmation by the International Committee on Taxonomy of Viruses (ICTV) , this group was known as the " PRD1 adenovirus lineage ". The taxon is named after Dennis H. Bamford, who first postulated the evolutionary relationship of all viruses DJR main capsid proteins.

Systematics

Adenoviruses in the TEM

Virophage Mavirus (bottom left) and the associated giant virus CroV

The Bamfordvirae currently (as of March 2020) include the following phyla confirmed by ICTV :

Nucleocytoviricota ( smallpox and giant viruses )
Preplasmiviricota ( Maveriviricetes with Lavidaviridae and Tectiliviricetes with Adenoviridae and others)
The members of the proposed family “ Autolykiviridae ” also have DJR proteins, which is why they can also be assigned to this taxon, even if the exact position within the group of DJR viruses is currently (2018) unclear.

This system documents the extensive relationship between the giant viruses and their own virophages from the Lavidaviridae .
