Influenza virus neuraminidase.
Antiserum specific for influenza A2 neuraminidase was produced by immunization of rabbits with the purified enzyme which had been isolated by electrophoresis from the proteins of a detergent-disrupted AoA2 influenza virus recombinant [X-7 (Fl)]. This recombinant contained hemagglutinin of the Ao subtype and A2 neuraminidase. Antiserum to the isolated A2 neuraminidase did not react in any of fou...
متن کاملNeuraminidase inhibitors as anti-influenza virus agents.
Influenza virus neuraminidase (NA) catalyses the cleavage of sialic acid residues terminally linked to glycoproteins and glycolipids and plays an important role in the replication of the virus. Recently, several potent NA inhibitors have been synthesized based on the rational design of mimicking the transition state of the sialic acid cleavage. Zanamivir and oseltamivir (GS 4104, the prodrug of...
متن کاملLoss of glycosylation at Asn144 alters the substrate preference of the N8 influenza A virus neuraminidase.
Role of asparagine-linked (N-linked) oligosaccharide side chains in the maturation and the function of influenza virus neuraminidase (NA) subtype N8 was examined by site-directed mutagenesis and vaccinia virus expression system. Mutations in the consensus sequence for N-linked glycosylation at Asn 84 or 398 prevent the proper maturation of mutant NAs. On the contrary, mutation at Asn 144, that ...
متن کاملInfluenza Virus Neuraminidase: Structure and Function
The structure of the influenza virus neuraminidases, the spatial organization of their active site, the mechanism of carbohydrate chains desialylation by neuraminidase, and its role in the influenza virus function at different stages of the viral infectious cycle are considered in this review. Data on the neuraminidase substrate specificity and different approaches in studying the activity of t...
متن کاملAntibody response in man to influenza virus neuraminidase following influenza.
Genetic recombination of influenza viruses of different subtype may result in segregation of hemagglutinin and neuraminidase in antigenically hybrid viruses [E. D. Kilbourne et al., in M. Pollard (ed.), Perspectives in Virology, vol. 5, p. 87, Academic Press, Inc., N.Y., 1967; and W. G. Laver and E. D. Kilbourne, Virology 30:493, 1966]. The selective use of such antigenic hybrids in serological...
