obsolete glucosaminylgalactosylglucosylceramide beta-galactosyltransferase activity (obsolete GO:0047275)
OBSOLETE. Catalysis of the reaction: N-acetyl-D-glucosaminyl-(1,3)-D-galactosyl-(1,4)-D-glucosylceramide + UDP-galactose = D-galactosyl-N-acetyl-D-glucosaminyl-(1,3)-D-galactosyl-(1,4)-D-glucosylceramide + UDP.
