Fig. 4From: Emergence of norovirus GII.P16-GII.2 strains in patients with acute gastroenteritis in Huzhou, China, 2016–2017Amino acid variations in the VP1 protein of NoV GII.P16-GII.2 strains. The conserved HBGA-binding interfaces and predicted epitopes in GII.2 are indicated by empty rectangles. GII.P16-GII.2 strains identified in Huzhou are designated by accession number, sample number, isolate time. Reference sequences are indicated by their accession number, strain name, year and countryBack to article page
