Figure 3.

A screen-shot of the EpitopeViewer demonstrating electrostatic contacts between Glu199 neuraminidase residue (shown in blue) and antibody residues Tyr33 of CDR H1 (colored in magenta), Arg52 of CDR H2 (colored in green) and Tyr94 of CDR L3 (colored in red). Salt bridges and hydrogen bonds are shown by red and yellow dotted lines, respectively. Status of the "Status" bar corresponds to the mouse position showing the contact between Glu199 and Arg52 of CDR H2.
