DE RecName: Full=Neuraminidase {ECO:0000256|RuleBase:RU361252, ECO:0000256|SAAS:SAAS00114532}; DE EC=3.2.1.18 {ECO:0000256|RuleBase:RU361252, ECO:0000256|SAAS:SAAS00114514}; DE Flags: Fragment; GN Name=NA {ECO:0000256|RuleBase:RU361252, ECO:0000313|EMBL:ACS45192.1}; OS Influenza A virus (A/Dublin/04/2009(H1N1)). OC Viruses; ssRNA viruses; ssRNA negative-strand viruses; OC Orthomyxoviridae; Alphainfluenzavirus. OX NCBI_TaxID=653735 {ECO:0000313|EMBL:ACS45192.1}; RN [1] {ECO:0000313|EMBL:ACS45192.1} RP NUCLEOTIDE SEQUENCE. RC STRAIN=A/Dublin/04/2009 {ECO:0000313|EMBL:ACS45192.1}; RA Carr M.J., Duffy M., Tuite G., Hall W.W.; RT "Human infection with novel swine-lineage H1N1 influenza virus in RT Ireland."; RL Submitted (JUN-2009) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the removal of terminal sialic acid residues CC from viral and cellular glycoconjugates. CC {ECO:0000256|RuleBase:RU361252}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha- CC (2->8)- glycosidic linkages of terminal sialic acid residues in CC oligosaccharides, glycoproteins, glycolipids, colominic acid and CC synthetic substrates.; EC=3.2.1.18; CC Evidence={ECO:0000256|RuleBase:RU361252, CC ECO:0000256|SAAS:SAAS01126145}; CC -!- COFACTOR: CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; CC Evidence={ECO:0000256|RuleBase:RU361252, CC ECO:0000256|SAAS:SAAS00612833}; CC -!- ACTIVITY REGULATION: Inhibited by the neuraminidase inhibitors CC zanamivir (Relenza) and oseltamivir (Tamiflu). These drugs CC interfere with the release of progeny virus from infected cells CC and are effective against all influenza strains. Resistance to CC neuraminidase inhibitors is quite rare. CC {ECO:0000256|SAAS:SAAS01070481}. CC -!- SUBUNIT: Homotetramer. {ECO:0000256|RuleBase:RU361252, CC ECO:0000256|SAAS:SAAS00114476}. CC -!- SUBCELLULAR LOCATION: Host apical cell membrane CC {ECO:0000256|RuleBase:RU361252, ECO:0000256|SAAS:SAAS00582107}; CC Single-pass type II membrane protein CC {ECO:0000256|RuleBase:RU361252, ECO:0000256|SAAS:SAAS00582107}. CC Virion membrane {ECO:0000256|RuleBase:RU361252}. CC -!- PTM: N-glycosylated. {ECO:0000256|RuleBase:RU361252}. CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 34 family.
