''Ligamenvirales'' is an order of linear viruses that infect archaea of the kingdom Crenarchaeota and have double-stranded DNA genomes. The order was established by D. Prangishvili and M. Krupovic in 2012. The name is derived from the Latin ligamen, meaning ''string'' or ''thread''. ==Taxonomy== 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.〔Goulet A, Blangy S, Redder P, Prangishvili D, Felisberto-Rodrigues C, Forterre P, Campanacci V, Cambillau C (2009) Acidianus filamentous virus 1 coat proteins display a helical fold spanning the filamentous archaeal viruses lineage. PNAS 106 (50) 21155–60〕 Viruses from the two families share up to ten genes. The genome is non segmented linear double stranded DNA. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Ligamenvirales」の詳細全文を読む スポンサード リンク
