SARS冠状病毒被确定为2003年全球爆发的SARS(严重急性呼吸系统综合症)的病原体。它的大RNA基因组编码4种结构蛋白,16种非结构蛋白和8种辅助蛋白。SARS冠状病毒大分子结构的可用性使其重要功能得以阐明,例如介导病毒和宿主细胞膜的融合,以及复制和转录。特别是,刺突蛋白融合核心和主要蛋白酶已被广泛研究,目的是设计抗sars治疗方法。现在的注意力集中在复制酶蛋白上,这将增强我们对复制和转录机制的理解。大多数SARS蛋白的结构和功能尚不清楚,进一步的结构研究对于揭示其功能和设计潜在的抗SARS治疗方法非常重要。
The SARS coronavirus was identified as the pathogen of a global outbreak of SARS (severe acute respiratory syndrome) in 2003. Its large RNA genome encodes four structural proteins, sixteen non-structural proteins and eight accessory proteins. The availability of structures of SARS coronavirus macromolecules has enabled the elucidation of their important functions, such as mediating the fusion of viral and host cellular membranes, and in replication and transcription. In particular, the spike protein fusion core and the main protease have been the most extensively studied, with the aim of designing anti-SARS therapeutics. Attention is now being focused on replicase proteins, which should enhance our understanding of the replication and transcription machinery. The structures and functions of most SARS proteins remain unknown, and further structural studies will be important for revealing their functions and for designing potential anti-SARS therapeutics.
