Figure 1From: Characterization of an H3N2 triple reassortant influenza virus with a mutation at the receptor binding domain (D190A) that occurred upon virus transmission from turkeys to pigsHA structure with Asp to Ala mutation at residue 190 of the RBD. The 3D structure of the HA molecule was downloaded from Protein Data Bank webpage (http://www.pdb.org; 1HGG-A/Aichi/2/68 (H3)) and modified using the PYMOL Molecular Graphics System (DeLano Scientific, San Carlos, CA). a: top view of the HA molecule; b: side view of the HA molecule. Red: RBD. Blue balls: Residue 190 of the RBD.Back to article page
