- Neuraminidase is a glycohydrolase. Neuraminidase hydrolyzes terminal N- or O-acyl-neuraminic acids that are α2,3-, α2,6-, or α2,8-linked to galactose, Hex, NAc, or N- or O-acylated neuraminyl residues in oligosaccharides/glycoconjugates or colominic acid. Relative rate of cleavage is α2→3 >α2→6 >α2→8, determined on bonds in tri- and tetrasaccharides.
- Neuraminidase hydrolyzes terminal N- or O-acetylneuraminic acids which are α2,3-, α2,6-, α2,8- linked to oligosaccharides, polysaccharides, mucopolysaccharides, glycoproteins, and glycolipids. For the hydrolysis of glycolipids, the presence of a detergent is necessary. Roche's Neuraminidase is very well suited for structural research studies on glycoconjugates and for hydrolytic cleavage of sialic acid from biological material.
