+
-
'''Sialidase''' is a neuraminidase which cleaves terminal sialic acid from a variety of natural substances <ref>PMID:12374200</ref>. The sialic acid-binding domain of sialidase is called CBD. For '''Anhydrosialidase''' catalyzes the elimination of sialyl group in N-acetylneuraminic acid glycosides to yield 2,7-anhydro-α-N-acetylneuraminate. For '''Trans-sialidase''' see [[Neuraminidase]].
