Tamiflu was designed to fit N2/N9, so it is serendipitous that it works on N1. In fact, when the structure of N1 was determined<ref name='Russell2006' />, the <font color='#e07000'><b>loop comprising residues 147-152</b></font> was not in a suitable position to participate in binding Tamiflu. However, the complex of N1 with Tamiflu revealed that this loop is pulled into proper contact with the drug in an [[Induced fit|induced fit]] manner<ref name='Russell2006' />. A [[Morphs|morph]] from N1 alone ([[2hty]]) to N1 complexed with Tamiflu ([[2hu4]])<ref>Chain A from [[2hty]] was morphed to chain A of [[2hu4]] by linear interpolation, inserting 6 intermediate interpolated frames, using the freely available [http://www.umass.edu/microbio/rasmol/pdbtools.htm#martz morph2 program].</ref> shows the change in position of this loop (<scene name='Avian_Influenza_Neuraminidase,_Tamiflu_and_Relenza/Morph_2hty_to_2hu4/8'>replay initial morph</scene>).

The binding of Tamiflu to N1 pulls the sidechains of two conserved residues, <scene name='Avian_Influenza_Neuraminidase,_Tamiflu_and_Relenza/Morph_2hty_to_2hu4/7'>Asp151, Glu119</scene>, closer to the inhibitor.
