neu·ra·min·i·dase N0070785 (no͝or′ə-mĭn′ĭ-dās′, -dāz′, nyo͝or′-)n. A hydrolytic enzyme that removes sialic acid from glycoproteins and is found in many cells and viruses. It occurs on the surface of influenza viruses and enables the release of newly replicated viruses from infected cells.
[neuramin(ic acid) (neur(o)- + amin(e)) + -id(e) + -ase.]neuraminidase (ˌnjʊərəˈmɪnɪdeɪz) n (Biochemistry) any of various enzymes, found esp in viruses, that catalyse the breakdown of glucosides containing neuraminic acid, an amino sugar[C20: from neuramin(ic acid) (from neuro- + amine + -ic) + -ide + -ase]neuraminidaseenUK
neuraminidase[‚nu̇r·ə′min·ə‚dās] (microbiology) A bacterial enzyme that acts to split salic acid from neuraminic acid glycosides. neuraminidaseenUK
sialidase [si-al´ĭ-dās] 1. an enzyme of the hydrolase class that catalyzes the cleavage of glucosidic linkages between a sialic acid" >sialic acid residue and a hexose" >hexose or hexosamine" >hexosamine residue at the nonreducing terminal of oligosaccharides in glycoproteins, glycolipids, and proteoglycans. Deficiency of it is an autosomal recessive trait and is seen in sialidosis" >sialidosis and galactosialidosis" >galactosialidosis.2. the enzyme with this activity specifically cleaving sialic acid–containing gangliosides; it is deficient in mucolipidosis IV" >mucolipidosis IV. Called also neuraminidase.si·al·i·dase (sī-al'i-dās), An enzyme that catalyzes the hydrolysis of terminal acetylneuraminic residues from oligosaccharides, glycoproteins, or glycolipids; present on the surface antigen in myxoviruses; used in histochemistry to selectively remove sialomucins, as from bronchial mucous glands and the small intestine; a deficiency of this enzyme produces sialidosis. Synonym(s): neuraminidaseneuraminidase (no͝or′ə-mĭn′ĭ-dās′, -dāz′, nyo͝or′-)n. A hydrolytic enzyme that removes sialic acid from glycoproteins and is found in many cells and viruses. It occurs on the surface of influenza viruses and enables the release of newly replicated viruses from infected cells.FinancialSeenThesaurusSeeN |
