Blood-group-substance endo-1,4-β-galactosidase (EC 3.2.1.102, endo-β-galactosidase, blood-group-substance 1,4-β-D-galactanohydrolase) is an enzyme with systematic name blood-group-substance 4-β-D-galactanohydrolase.[1][2][3] It catalyses endohydrolysis of (1→4)-β-D-galactosidic linkages in blood group A and B substances.
It hydrolyses the 1,4-β-D-galactosyl linkages adjacent to a 1,3-α-D-galactosyl or N-acetylgalactosaminyl residues and a 1,2-α-D-fucosyl residue.
