Enzyme Commission Primary Name: blood-group-substance endo-1,4-β-galactosidase
Enzyme Commission Synonyms: endo-β-galactosidase, blood-group-substance 1,4-β-D-galactanohydrolase
Enzyme Commission Summary:
This enzyme catalyzes endohydrolysis of (1→4)-β-D-galactosidic linkages in blood group A and B substances.
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.
