Molecular docking of different NA substrates and inhibitors. a Oseltamivir versus H7N9 original strain, b Oseltamivir versus H7N9 R to K 292 mutant strain, c Zanamivir versus H7N9 original strain, d Zanamivir versus H7N9 R to K 292 mutant strain, e Peramivir versus H7N9 original strain, f Peramivir versus H7N9 R to K 292 mutant strain, g Laninamivir versus H7N9 original strain, h Laninamivir versus H7N9 R to K 292 mutant strain. N7 amino acid numbering was used to allocate amino acid in the binding pocket of the neuraminidase
