Keratan-sulfate endo-1,4-β-galactosidase (EC 3.2.1.103, endo-β-galactosidase, keratan sulfate endogalactosidase, keratanase, keratan-sulfate 1,4-β-D-galactanohydrolase) is an enzyme with systematic name keratan-sulfate 4-β-D-galactanohydrolase.[1] It catalyses endohydrolysis of (1→4)-β-D-galactosidic linkages in keratan sulfate.

It hydrolyses the 1,4-β-D-galactosyl linkages adjacent to 1,3-N-acetyl-α-D-glucosaminyl residues.
