Guttaviridae
CAS4 and PolA containing viruses in hyperthermophiles
SpiraVirus -ss circular DNA virus -ACV
deltaviruses –circular ssDNA viruses dependent on Hepatitis B in humans but not in other animals. contain a rna endonculease ribozyme and code the the delta antigen that forms helical rod shaped structures with ds RNA. Structure of delta antigen capsid has a core with 4 helical loops… similar to the cas4 family. May have evolved from viroids.
