Fig. 4From: The resurgence of the norovirus GII.4 variant associated with sporadic gastroenteritis in the post-GII.17 period in South China, 2015 to 2017Evolutionary tracing of variable sites on the capsid P2 subdomain of GII.4–2012 strains. All variable sites are marked by asterisks below. Conserved amino acid sites in five epitopes A-E were only listed for the GII.4–2012 variant, and then replaced by dashes “-” for different clades and clusters. The specific amino acid substitution N373 for Cluster A is highlighted in light grayBack to article page
