Enzyme Information

Endo-alpha-sialidase.
based on mapping to UniProt Q04830
Endohydrolysis of (2->8)-alpha-sialosyl linkages in oligo- or poly(sialic) acids.
-!- Although the name endo-N-acetylneuraminidase has also been used for this enzyme, this is misleading since its activity is not restricted to acetyl-substituted substrates. -!- An exo-alpha-sialidase activity is listed as EC 3.2.1.18. -!- See also 4.2.2.15.
