neuraminidase /neu·ra·min·i·dase/ (-ah-min´ĭ-dās) an enzyme of the surface coat of myxoviruses that destroys the neuraminic acid of the cell surface during attachment, thereby preventing hemagglutination.
neuraminidase
neu·ra·min·i·dase (n r  -m n -d s, -dz)n. An enzyme that catalyzes the hydrolysis of terminal acylneuraminic residues from oligosaccharides, glycoproteins, and glycolipids. It is present as a surface antigen in myxoviruses. Also called sialidase. |
neuraminidase
[noo͡r′əmē′nədās]
an enzyme that catalyzes the cleavage of N-acetyl neuraminic acid from mucopolysaccharides. A hereditary deficiency of the enzyme causes sialidosis and is associated with galactogialidosis; it is characterized by mental retardation and skeletal changes, especially dysotosis multiplex. Also called sialidase. See also sialidosis.
neuraminidase
1. an enzyme that cleaves the terminal N-acetylneuraminic acid from mucoproteins.
2. a structural component occurring as a spike in the envelope of ortho- and paramyxoviruses.
