ID 3.2.1.103 DE keratan-sulfate endo-1,4-beta-galactosidase. AN endo-beta-galactosidase. CA Endohydrolysis of (1->4)-beta-D-galactosidic linkages in keratan sulfate. CC -!- Hydrolyzes the 1,4-beta-D-galactosyl linkages adjacent to 1,3-N- CC acetyl-alpha-D-glucosaminyl residues. CC -!- Also acts on some non-sulfated oligosaccharides, but only acts on CC blood group substances when the 1,2-linked fucosyl residues have been CC removed (cf. EC 3.2.1.102).
