IntEnz Enzyme Nomenclature
EC 3.2.1.18

Names

Accepted name:

exo-α-sialidase

Other names:

α-neuraminidase
acetylneuraminidase
neuraminidase
sialidase
N-acylneuraminate glycohydrolase

Systematic name:

acetylneuraminyl hydrolase

Reaction

Hydrolysis of α-(2→3)-, α-(2→6)-, α-(2→8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates.

Comments:

The enzyme does not act on 4-O-acetylated sialic acids. An endo-α-sialidase activity is listed as EC 3.2.1.129 endo-α-sialidase. See also EC 4.2.2.15 anhydrosialidase.
