Figure 2
(a) Sequence alignment of the NT60 (H3N2), WSN (H1N1) and HK97 (H5N1) NP sequences. (b) Ribbon representation of the NT60 R416A NP showing amino-acid sequence conservation between the NT60, WSN and HK97 NPs (grey, conserved; orange, one sequence differs; purple, all three sequences differ). (c) Surface representation of the NT60 R416A NP showing the surface-charge distribution (blue, basic; red, acidic). (d) Top: the electron density (level 1.0) of residues 78–90 in the NT60 R416A H3N2 structure. Bottom: a comparison to the positioning of the 73–90 loop in the WSN R416A and HK97 NP structures.
