Sysname
UDP-alpha-D-galactose:beta-D-galactosyl-(1->4)-beta-N-acetyl-D-glucosaminyl-R 3-alpha-D-galactosyltransferase
Reaction(IUBMB)
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 (where R can be OH, an oligosaccharide or a glycoconjugate) [RN:R02791]
Reaction(KEGG)
R02791 > R04531 R05978(G) R06145(G) R06169(G);
(other) R11320(G)
Substrate
UDP-alpha-D-galactose [CPD:C00052];
beta-D-galactosyl-(1->4)-beta-N-acetyl-D-glucosaminyl-R
Product
UDP [CPD:C00015];
alpha-D-galactosyl-(1->3)-beta-D-galactosyl-(1->4)-beta-N-acetylglucosaminyl-R [CPD:C04855]
Comment
Acts on beta-galactosyl-1,4-N-acetylglucosaminyl termini on asialo-alpha1-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.
