MD simulations of 09-1B12-UCA in contact with H3 (A/Perth/16/2009) or H7 (A/Shanghai/02/2013) trimers N55T. The color gradient on the surface indicates the interaction time for hydrogen bonds and charged interactions (darker colors means longer interaction time). See alsoTable S4(in relation to A and B) andFigure S1andTable S1(in relation to D, G, and I).
