(A) Crystal structures of rotavirus VP8*s. Phylogenetic analysis of VP8*s of 35 RV P genotypes (circular dendrogram) was conducted by MEGA6 using the neighbor-joining method. The crystal structures of VP8*s in complex with glycans are presented. P[3], Rhesus rotavirus RRV in complex with Sia, rainbow, PDB ID: 1KQR. P[7], CRW-7 in complex with sia, teal, PDB ID: 3TAY. P[14], human rotavirus HAL1166 in complex with A-type HBGA, cyan, PDB ID: 4DRV. P[9], human rotavirus K8 in complex with A-type HBGA, Aquamarine, PDB ID: 5CB7. P[11], human neonatal rotavirus N155 in complex with type II tetrasaccharide LNnT, salmon, PDB ID: 4YG0. P[11], bovine rotavirus B223 in complex with type II tetrasaccharide LNnT, lightpink, PDB ID: 4YG6. P[6], human rotavirus RV3 in complex with LNFP1, skyblue, PDB ID: 6OAI. P[19], human rotavirus MC345 in complex with LNT, green, PDB ID: 5YMT. P[4], human rotavirus DS-1 in complex with LNFP1, warmpink, PDB ID: 5VX5. P[8], human rotavirus Rotateq in complex with LNFP1, yellow, PDB ID: 6K2O. (B) Phylogenetic analysis of VP8*s of 50 RV P genotypes (circular dendrogram) was conducted by MEGA6 using the neighbor-joining method.
