Reaction catalysed
UDP-galactose + beta-D-galactosyl-(1->4)-beta-N-acetyl-D-glucosaminyl-R <=> UDP + alpha-D-galactosyl-(1->3)-beta-D-galactosyl-(1->4)-beta-N-acetylglucosaminyl-R
Comment(s)
  • Acts on beta-galactosyl-1,4-N-acetylglucosaminyl termini on asialo- alpha(1)-acid glycoprotein and N-acetyllactosamine (beta-D- galactosyl-1,4-N-acetyl-beta-D-glucosamine), but not on 2'-fucosylated-N-acetyllactosamine.
  • The non-reducing terminal N-acetyllactosamine residues of glycoproteins can also act as acceptor.
  • Now includes EC 2.4.1.124 and EC 2.4.1.151.
