31. Antigenic and genome sequencing suggests that H7N9 is sensitive to neuraminidase inhibitors, such as oseltamivir and zanamivir. 32. The Hong Kong flu strain shared internal genes and the neuraminidase with the 1957 Asian Flu ( H2N2 ). 33. The Hong Kong flu strain shared internal genes and the neuraminidase with the 1957 Asian flu ( H2N2 ). 34. Hemagglutinin-neuraminidase inhibitors have been investigated and suggest that there may applications for human use in the future. 35. The hemagglutinin ( HA ) and neuraminidase ( NA ) proteins are shown on the surface of the particle. 36. Glycoside hydrolase family 34 CAZY GH _ 34 comprises enzymes with only one known activity; sialidase or neuraminidase . 37. The C8 and C9 diol play an important role in the binding affinity with neuraminidase , prolonging the effect. 38. Relenza will be the first of a new class of flu medicines known as neuraminidase inhibitors to reach the market. 39. Peramivir is a neuraminidase inhibitor, acting as a neuraminidase and thereby preventing new viruses from emerging from infected cells. 40. Peramivir is a neuraminidase inhibitor, acting as a neuraminidase and thereby preventing new viruses from emerging from infected cells.
