Chain A,B,C (HN_NDVB | P32884)

molecular function
	GO:0052794	exo-alpha-(2->3)-sialidase activity	Catalysis of the hydrolysis of alpha-(2->3)-glycosidic linkages of terminal sialic residues in substrates.
	GO:0052795	exo-alpha-(2->6)-sialidase activity	Catalysis of the hydrolysis of alpha-(2->6)-glycosidic linkages of terminal sialic residues in substrates.
	GO:0052796	exo-alpha-(2->8)-sialidase activity	Catalysis of the hydrolysis of alpha-(2->8)-glycosidic linkages of terminal sialic residues in substrates.
	GO:0004308	exo-alpha-sialidase activity	Catalysis of the hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)-glycosidic linkages of terminal sialic residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates.
	GO:0046789	host cell surface receptor binding	Interacting selectively and non-covalently with a receptor on the host cell surface.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
biological process
	GO:0046718	viral entry into host cell	The process that occurs after viral attachment by which a virus, or viral nucleic acid, breaches the plasma membrane or cell envelope and enters the host cell. The process ends when the viral nucleic acid is released into the host cell cytoplasm.
	GO:0019058	viral life cycle	A set of processes which all viruses follow to ensure survival; includes attachment and entry of the virus particle, decoding of genome information, translation of viral mRNA by host ribosomes, genome replication, and assembly and release of viral particles containing the genome.
	GO:0016032	viral process	A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
	GO:0019062	virion attachment to host cell	The process by which a virion protein binds to molecules on the host cellular surface or host cell surface projection.
cellular component
	GO:0033644	host cell membrane	Double layer of lipid molecules as it encloses host cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. The host is defined as the larger of the organisms involved in a symbiotic interaction.
	GO:0020002	host cell plasma membrane	The plasma membrane surrounding a host cell.
	GO:0016021	integral component of membrane	The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0019031	viral envelope	The lipid bilayer of a virion that surrounds the protein capsid. May also contain glycoproteins.
	GO:0019012	virion	The complete fully infectious extracellular virus particle.
	GO:0055036	virion membrane	The lipid bilayer surrounding a virion.
