单纯疱疹病毒(HSV)引起人类口腔和生殖器溃疡疾病。HSV-2患者有更高的风险获得人类免疫缺陷病毒感染。HSV-2是α-疱疹病毒亚科的成员,其与β-和γ-疱疹病毒亚科一起形成疱疹病毒科。在这里,我们报告的冷冻电镜结构的HSV-2的C-衣壳与衣壳顶点特异性组件(CVSC),确定在3.75 ℃使用基于块的重建策略。我们提出了多种构象的衣壳蛋白(VP 5,VP 23,VP 19 C和VP 26)和CVSC的原子模型。HSV-2同源物的比较产生了关于三种疱疹病毒亚科之间结构相似性和差异的信息,并且我们鉴定了α-疱疹病毒特异性结构特征。由UL 17单体、UL 25二聚体和UL 36二聚体组成的异源五聚体CVSC通过五螺旋束紧密结合,所述五螺旋束形成与周围衣壳蛋白接触的广泛亚基网络,这增强了衣壳稳定性。单纯疱疹病毒2型(HSV-2)属于α-疱疹病毒亚科,是一种引起生殖器溃疡疾病的性传播病毒。在此,作者展示了具有衣壳顶点特异性组分的HSV-2 C-衣壳的3.75 kDa冷冻电镜结构,并描述了α-疱疹病毒特异性结构特征。
Herpes simplex viruses (HSVs) cause human oral and genital ulcer diseases. Patients with HSV-2 have a higher risk of acquiring a human immunodeficiency virus infection. HSV-2 is a member of the α-herpesvirinae subfamily that together with the β- and γ-herpesvirinae subfamilies forms the Herpesviridae family. Here, we report the cryo-electron microscopy structure of the HSV-2 C-capsid with capsid-vertex-specific component (CVSC) that was determined at 3.75 Å using a block-based reconstruction strategy. We present atomic models of multiple conformers for the capsid proteins (VP5, VP23, VP19C, and VP26) and CVSC. Comparison of the HSV-2 homologs yields information about structural similarities and differences between the three herpesviruses sub-families and we identify α-herpesvirus-specific structural features. The hetero-pentameric CVSC, consisting of a UL17 monomer, a UL25 dimer and a UL36 dimer, is bound tightly by a five-helix bundle that forms extensive networks of subunit contacts with surrounding capsid proteins, which reinforce capsid stability. Herpes simplex virus type-2 (HSV-2) belongs to the α-herpesvirinae subfamily and is a sexually transmitted virus that causes genital ulcer disease. Here the authors present the 3.75 Å cryo-EM structure of the HSV-2 C-capsid with capsid-vertex-specific component and describe α-herpesvirus-specific structural features.
