Dengue virus belongs to the Flaviviridae family, being responsible for an endemic arboviral disease in humans. It is an enveloped virus, whose genome is a positive-stranded RNA packaged by the capsid protein. Dengue virus capsid protein (DENVC) forms homodimers in solution organized in 4 α-helices and an intrinsically disordered N-terminal region. The N-terminal region is involved in the binding of membranous structures in host cells and in the recognition of nucleotides. Here we report the H, N and C resonance assignments of the DENVC with the deletion of the first 19 intrinsically disordered residues. The backbone chemical shift perturbations suggest changes in the α1 and α2 helices between full length and the truncated proteins.
登革热病毒属于黄病毒科,是一种地方性虫媒病毒病。它是一种包膜病毒,其基因组是由衣壳蛋白包装的正链 RNA。登革热病毒衣壳蛋白(DENVC)在溶液中形成同源二聚体,由 4 个α-螺旋和一个内在无序的 N 端区域组成。N 端区域参与与宿主细胞中膜结构的结合以及核苷酸的识别。本文报道了缺失前 19 个内在无序残基的 DENVC 的 H、N 和 C 共振归属。骨架化学位移扰动表明全长蛋白和截短蛋白的α1 和α2 螺旋之间发生了变化。
