| sialidase | <enzyme> Enzyme catalysing cleavage of neuraminic acid residues from oligosaccharide chains of glycoproteins and glycolipids. Since these residues are usually terminal, neuraminidases are generally exo enzymes, although an endoneuraminidase is known. For use as a laboratory reagent, common sources are from bacteria such as Vibrio or Clostridium. A neuraminidase is one of the transmembrane proteins of the envelope of influenza virus.

| sialidase |
1. an enzyme of the hydrolase class that catalyzes the cleavage of glucosidic linkages between a sialic acid residue and a hexose or hexosamine residue at the nonreducing terminal of oligosaccharides in glycoproteins, glycolipids, and proteoglycans. Deficiency of the enzyme, an autosomal recessive trait, causes sialidosis; enzyme activity is also lacking in galactosialidosis. In EC nomenclature, called exo-α-sialidase. 2. the enzyme with this activity specifically cleaving sialic acidcontaining gangliosides; it is deficient in mucolipidosis IV. Called also neuraminidase.
