Ligamenvirales is an order of linear viruses that infect archaea of the kingdom Crenarchaeota and have double-stranded DNA genomes.[1]
The name is derived from the Latin ligamen, meaning string or thread.
Taxonomy [edit]
There are two families in this order - Lipothrixviridae and Rudiviridae.
The virons are filamentous with a helical nucleocapsid. At either end are attached either fibers or more complex structures involved in host adhesion.
The major coat proteins of both lipothrixviruses and rudiviruses have an unusual four-helix bundle topology.[2] Viruses from the two families share up to ten genes.
The genome is non segmented linear double stranded DNA.
