Hydrolyses the 1,4-¦Â-D-galactosyl linkages adjacent to 1,3-N-acetyl-¦Á-D-glucosaminyl residues. Also acts on some non-sulfated oligosaccharides, but only acts on blood group substances when the 1,2-linked fucosyl residues have been removed (cf.?EC?3.2.1.102?blood-group-substance endo-1,4-¦Â-galactosidase).
