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: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.
    GO:0016798    hydrolase activity, acting on glycosyl bonds    Catalysis of the hydrolysis of any glycosyl bond.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
biological process
    GO:0005975    carbohydrate metabolic process    The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
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:0019012    virion    The complete fully infectious extracellular virus particle.
    GO:0055036    virion membrane    The lipid bilayer surrounding a virion.
