Hepatitis C virus (HCV) infection remains a major health problem worldwide. HCV entry into host cells and membrane fusion are achieved by two envelope glycoproteins, E1 and E2. We report here the 3.5-Å resolution crystal structure of the N-terminal domain of the HCV E1 ectodomain, which reveals a complex network of covalently linked intertwined homodimers that do not harbour the expected truncated class II fusion protein fold.
丙型肝炎病毒(HCV)感染仍是全球主要的健康问题。HCV通过两种包膜糖蛋白E1和E2进入宿主细胞并实现膜融合。我们在此报告HCV E1胞外域N端结构域的3.5埃分辨率晶体结构,该结构揭示了一个由共价连接的交织同型二聚体组成的复杂网络,这些同型二聚体不具有预期的截短的II类融合蛋白折叠结构。
