ENZYME entry: EC 3.2.1.103

Accepted Name
Keratan-sulfate endo-1,4-beta-galactosidase.
Alternative Name(s)
Endo-beta-galactosidase.
Reaction catalysed
Endohydrolysis of (1->4)-beta-D-galactosidic linkages in keratan sulfate
Comment(s)
  • Hydrolyzes the 1,4-beta-D-galactosyl linkages adjacent to 1,3-N- acetyl-alpha-D-glucosaminyl residues.
  • Also acts on some non-sulfated oligosaccharides, but only acts on blood group substances when the 1,2-linked fucosyl residues have been removed (cf. EC 3.2.1.102).
