Portogloboviridae is a family of viruses with circular, double-stranded DNA genomes of about 20 kbp. Their icosahedral virions have a diameter of 87 nm, and consist of an outer protein shell, an inner lipid layer and a nucleoprotein core wound up into a spherical coil. Portogloboviruses infect hyperthermophilic archaea of the genus Saccharolobus , order Sulfolobales and are presumably nonlytic. Portogloboviruses encode mini-CRISPR arrays which they use to compete against other co-infecting viruses. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Portogloboviridae, which is available at ictv.global/report/portogloboviridae.

ICTV 病毒分类学概况：Portogloboviridae


门球病毒科是具有约 20 kbp 的环状双链 DNA 基因组的病毒家族。它们的二十面体病毒粒子直径为 87 nm，由蛋白质外层、脂质内层和缠绕成球形线圈的核蛋白核心组成。门球病毒感染硫化叶菌目糖球菌属的超嗜热古菌，并且可能是非裂解性的。门球病毒编码微型 CRISPR 阵列，用于与其他共感染病毒竞争。这是国际病毒分类委员会 (ICTV) 关于门球病毒科报告的摘要，可在 ictv.global/report/portogloboviridae 上获取。
