Fig. 9From: A study on catalytic and non-catalytic sites of H5N1 and H1N1 neuraminidase as the target for chalcone inhibitorsThe molecular interactions of 2b with a non-catalytic H1N1, b catalytic H1N1, c non-catalytic H5N1, and d catalytic H5N1 NA sites. The green, pale green, purple, magenta, pink, cyan, yellowish-green and orange represent H-bond, vdW, pi-sigma, amide pi-stacked, pi-alkyl, pi-halogen, pi-lone pair electrons, and pi-cation/anion, respectivelyBack to article page
