Fig. 2From: A study on catalytic and non-catalytic sites of H5N1 and H1N1 neuraminidase as the target for chalcone inhibitorsThe superimposition of 10 chalcone derivatives (yellow sticks) in the non-catalytic site of a H1N1 and b H5N1 NA. The NA is presented in the surface model and the ligands are in the stick models, docked in the behind of the catalytic site (yellow circles)Back to article page
