Accepted name: sialate O-acetylesterase
Reaction: N-acetyl-O-acetylneuraminate + H2O = N-acetylneuraminate + acetate
Other name(s): N-acetylneuraminate acetyltransferase; sialate 9(4)-O-acetylesterase; sialidase
Systematic name: N-acyl-O-acetylneuraminate O-acetylhydrolase
Comments: Acts on free and glycosidically bound N-acetyl- or N-glycoloyl-neuraminic acid; acts mainly on the 4-O- and 9-O-acetyl groups. Also acts on some other O-acetyl esters, both cyclic and acyclic compounds, which are not sialic acids.
