寨卡病毒(ZIKV)是一种新出现的蚊媒黄病毒,是引起严重疾病的主要公共卫生问题。由于脂质膜和结构异质性的存在,获得原子分辨率的结构是具有挑战性的,但重要的是要了解病毒组装和生命周期机制,为治疗干预提供不同的目标。我们在这里使用子体积细化,以实现3.4 μ m分辨率的结构,并确定两个不同的脂质部分。第一个来自内小叶,并由M和E跨膜螺旋的疏水残基协调,形成先前未表征的结合口袋。第二个脂质来自两个E蛋白螺旋之间的外叶坐标。基于结构的诱变识别关键的疏水相互作用及其对病毒生命周期的影响。结果显示,脂质在ZIKV组装途径中起重要作用,揭示了基于脂质的抗病毒药物开发的潜在靶标。在本文中,作者提供了成熟寨卡病毒(ZIKV)的3.4 kDa分辨率结构,并鉴定了由M和E跨膜螺旋的疏水残基以及E蛋白的两个螺旋之间协调的两个脂质部分,这两个脂质部分在ZIKV组装途径中发挥重要作用。
Zika virus (ZIKV) is an emerging mosquito borne flavivirus and a major public health concern causing severe disease. Due to the presence of a lipid membrane and structural heterogeneity, attaining an atomic resolution structure is challenging, but important to understand virus assembly and life cycle mechanisms that offer distinct targets for therapeutic intervention. We here use subvolume refinement to achieve a 3.4 Å resolution structure and identify two distinct lipid moieties. The first arises from the inner leaflet and is coordinated by hydrophobic residues of the M and E transmembrane helices that form a binding pocket not previously characterized. The second lipid arises from the outer leaflet coordinate between two E protein helices. Structure-based mutagenesis identifies critical hydrophobic interactions and their effect on the virus life cycle. Results show that lipids play an essential role in the ZIKV assembly pathway revealing a potential target of lipid based antiviral drug development. Here, the authors provide a 3.4 Å resolution structure of mature Zika virus (ZIKV) and identify two lipid moieties, coordinated by hydrophobic residues of the M and E transmembrane helices and between two helices of E protein, that play an essential role in the ZIKV assembly pathway.
