NiceZyme View of ENZYME: EC 3.2.1.18

Official Name
Exo-alpha-sialidase.
Alternative Name(s)
Alpha-neuraminidase.
N-acylneuraminate glycohydrolase.
Neuraminidase.
Sialidase.
Reaction catalysed
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
Comment(s)
  • 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.
