Anellovirus

	Anellovirus ''Anelloviridae'' is a Family (biology), family of viruses. They are classified as vertebrate viruses and have a non-enveloped capsid, which is round with isometric, icosahedral symmetry and has a triangulation number of 3. The name is derived from Italian ''anello'' 'ring', referring to the circular genome of anelloviruses. Genome The genome is not segmented and contains a single molecule of cccDNA, circular, negative-sense, single-stranded DNA. The complete genome is 3000–4000 nucleotides long. They also contain a non-coding region with one to two 80–110 nt sequences that contain high GC content, forming a secondary structure of stems and loops. The genome has Open reading frame, ORFs and a high degree of genetic diversity. Although the mechanism of replication has not been studied heavily, anelloviridae appears to use the rolling circle mechanism where first ssDNA is converted to dsDNA. It requires a host polymerase for replication to occur as the genome itself does no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Gyrovirus ''Gyrovirus'' is a genus of viruses, in the family ''Anelloviridae''. Until 2011, chicken anemia virus was the only Gyrovirus identified, but since then gyroviruses have also been identified in humans. Diseases associated with this genus include: chicken infectious anemia, which is associated with depletion of cortical thymocytes and erythroblastoid cells. Taxonomy The genus contains the following species: * ''Chicken anemia virus'' * ''Gyrovirus fulga1'' * ''Gyrovirus galga1'' * ''Gyrovirus galga2'' * ''Gyrovirus homsa1'' * ''Gyrovirus homsa2'' * ''Gyrovirus homsa3'' * ''Gyrovirus homsa4'' * ''Gyrovirus hydho1'' * ''Gyrovirus myferr1'' Structure Gyroviruses have an average size of 19 to 27 nanometers. They are nonenveloped and have an icosahedral capsid with T=1 symmetry. The unique, single protein, trumpet-shaped capsomeres of ''Gyrovirus'' are arranged into 12 pentomers yielding a capsid 60 units in size. The genome is circular, non-segmented, and 2290–2320 nucleotides lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
