Enzyme Information

N-acetyllactosaminide 3-alpha-galactosyltransferase.
based on mapping to UniProt P14769
UDP-alpha-D-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.
-!- 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. -!- Formerly EC 2.4.1.124 and EC 2.4.1.151.
