Name |
endo-alpha-sialidase;
endo-N-acylneuraminidase;
endoneuraminidase;
endo-N-acetylneuraminidase;
poly(alpha-2,8-sialosyl) endo-N-acetylneuraminidase;
poly(alpha-2,8-sialoside) alpha-2,8-sialosylhydrolase;
endosialidase;
endo-N
|
Class |
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
|
Sysname |
polysialoside (2->8)-alpha-sialosylhydrolase
|
Reaction(IUBMB) |
Endohydrolysis of (2->8)-alpha-sialosyl linkages in oligo- or poly(sialic) acids
|
Comment |
Although the name endo-N-acetylneuraminidase has also been used for this enzyme, this is misleading since its activity is not restricted to acetylated substrates. An exo-alpha-sialidase activity is listed as EC 3.2.1.18 exo-alpha-sialidase. See also EC 4.2.2.15 anhydrosialidase.
