Keratan-sulfate endo-1,4-beta-galactosidase (EC 3.2.1.103, endo-beta-galactosidase, keratan sulfate endogalactosidase, keratanase, keratan-sulfate 1,4-beta-D-galactanohydrolase) is an enzyme with systematic name keratan-sulfate 4-beta-D-galactanohydrolase.[1] This enzyme catalyses the following chemical reaction

Endohydrolysis of (1->4)-beta-D-galactosidic linkages in keratan sulfate

Hydrolyses the 1,4-beta-D-galactosyl linkages adjacent to 1,3-N-acetyl-alpha-D-glucosaminyl residues.
