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
Other name(s): neuraminidase; sialidase; α-neuraminidase; acetylneuraminidase
Systematic name: acetylneuraminyl hydrolase
Comments: The enzyme does not act on 4-O-acetylated sialic acids. endo-α-Sialidase activity is listed as EC 126.96.36.199, endo-α-sialidase. See also EC 188.8.131.52 anhydrosialidase.
