The Flavitrack database groups Flaviviruses (FV), evolutionarily related organisms with high subtype variability, according to their phenotypes. Here, PCPMer tools were used to calculate consensus sequences based on conservation of Physicochemical Properties (PCP) for 919 sequences of NS2a, a non-structural protein involved in preventing host interferon response to infection. Conserved PCP-motifs were detected, primarily in the N-terminal half of NS2a. One model structure, based on a nuclear receptor, groups residues essential for West Nile (WN) infectivity (I59, V61, and M103) in a pocket on the protein surface. These methods will aid in the design of vaccines and specific therapies against FV.
Flavitrack数据库根据黄病毒(FV)的表型对其进行分组,黄病毒是进化相关且具有高亚型变异性的生物体。在此,使用PCPMer工具基于物理化学性质(PCP)的保守性计算了919条NS2a序列的共有序列,NS2a是一种参与阻止宿主对感染产生干扰素反应的非结构蛋白。检测到保守的PCP基序,主要位于NS2a的N端一半区域。一种基于核受体的模型结构将西尼罗河病毒(WN)感染性所必需的残基(I59、V61和M103)聚集在蛋白质表面的一个口袋中。这些方法将有助于设计针对黄病毒的疫苗和特异性疗法。
