Finnlakeviridae is a family of icosahedral, internal membrane-containing bacterial viruses with circular, single-stranded DNA genomes. The family includes the genus, Finnlakevirus, with the species, Flavobacterium virus FLiP. Flavobacterium phage FLiP was isolated with its Gram-negative host bacterium from a boreal freshwater habitat in Central Finland in 2010. It is the first described single-stranded DNA virus with an internal membrane and shares minimal sequence similarity with other known viruses. The virion organization (pseudo T=21 dextro) and major capsid protein fold (double-β-barrel) resemble those of Pseudoalteromonas phage PM2 (family Corticoviridae), which has a double-stranded DNA genome. A similar major capsid protein fold is also found in other double-stranded DNA viruses in the kingdom Bamfordvirae. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) report on the family Finnlakeviridae, which is available at ictv.global/report/finnlakeviridae.

ICTV病毒分类标准简介：Finnlakeviridae

Finnlakeviridae是具有二十面体，内膜的细菌病毒家族，具有环状单链DNA基因组。该家族包括黄杆菌病毒属，以及黄杆菌属细菌FLiP。黄病毒噬菌体FLiP与其革兰氏阴性宿主细菌于2010年从芬兰中部的一个淡水生境中分离出来。它是第一种描述的具有内膜的单链DNA病毒，与其他已知病毒的序列相似性极低。病毒体组织（伪T = 21 dextro）和主要衣壳蛋白折叠（双β-桶）类似于假单胞菌噬菌体PM2（Corticoviridae家族）），具有双链DNA基因组。在Bamfordvirae王国的其他双链DNA病毒中也发现了类似的主要衣壳蛋白折叠。这是国际病毒分类委员会（ICTV）关于Finnlakeviridae家族报告的摘要，该报告可在ictv.global/report/finnlakeviridae中获得。
