Exo-alpha-sialidase.
based on mapping to UniProt P62575
Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates.
-!- The enzyme does not act on 4-O-acetylated sialic acids. -!- An endo-alpha-sialidase activity is listed as EC 3.2.1.129. -!- See also EC 4.2.2.15.
