Endo-alpha-sialidase (EC 3.2.1.129, 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) is an enzyme with systematic name polysialoside (2->8)-alpha-sialosylhydrolase.[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction:

Endohydrolysis of (2->8)-alpha-sialosyl linkages in oligo- or poly(sialic) acids
