Definitions for "Neuraminidase"
An antigenic glycoprotein enzyme found on the surface of the Influenza virus which forms a mushroom-shaped projection. The enzyme assists in the release of newly-formed virus particles from the surface of an infected cell. Neuraminidase cleaves terminal sialic acid residues from carbohydrate moieties on the surfaces of infected cells. This promotes the release of progeny viruses from infected cells.
sialidase; an enzyme that catalyzes the hydrolysis of glucosidic linkages between a sialic acid residue and a hexose or hexosamine residue in glycoproteins, glycolipids, and proteoglycans. Neuraminidase is a major antigen of myxoviruses.
Neuraminidase is an enzyme that cleaves terminal acylneuraminic residues from oligosaccharides, glycoproteins, or glycolipids; present as a surface antigen in myxoviruses. It is also used in histochemistry to selectively remove sialomucins as from bronchial mucous glands and the small intestine.
