Noroviruses (NoVs), an important cause of gastroenteritis in humans, recognize human histo-blood group antigens (HBGAs) as receptors. The crystal structures of the protruding (P) domain of a GII.10 NoV (Vietnam 026) in complex with various HBGA oligosaccharides were elucidated. However, the HBGA binding profile of this virus remains unknown. In this study, we determined the saliva and oligosaccharide binding profiles of this virus and the roles of amino acids that are involved in HBGA binding. Our data showed that Vietnam 026 bound to all ABO secretor and non-secretor saliva with clear signals detected by monoclonal antibodies against H3, H1, Le(y), Le(a) and sialyl Le(a). Mutagenesis study confir... More
