ABSTRACT
Objective@#During the 2016 winter season, GII.2 norovirus(NoV) suddenly emerged in China. To elucidate its mechanism of epidemic, this study focused on characteristics of binding between the P protein of capsid and histo-blood group antigens (HBGAs).@*Methods@#The research object was GⅡ.2 ZTX strain which had an outbreaks by the end of 2016 in Beijing. Recombinant prokaryotic expression plasmid was constructed, and the expression of virus P protein was determined and purified. The P protein characteristics of binding to HBGAs was studied through saliva and oligosaccharide binding experiments.@*Results@#Soluble P protein was successfully obtained, and combined with type A, B, AB saliva.@*Conclusions@#The result illuminate the combination with new outbreaks of NoV and salivary types, which provided a basis for its pathogenic mechanism and prevention and control measures.
