β-N-acetylglucosaminylglycopeptide β-1,4-galactosyltransferase M-CSA #570 | Beta-1,4-galactosyltransferase-1 (Gal-T1) is a Golgi resident type II protein that catalyses the transfer of galactose from UDP-Gal to N-acetylglucosamine in the presence of Mg2+, forming the product N-acetyl-lactosamine. The 1-4- galactosyltransferase (Gal-T) family, consists of at least seven members, including Gal-T1, with a 25 to 55% sequence homology. These enzymes are expressed in different tissues and show differences in the oligosaccharide acceptor specificity. | Defined by 8 residues: ASP:A-138 [auth A-252]ASP:A-140 [auth A-254]TRP:A-200 [auth A-314]GLU:A-203 [auth A-317]ASP:A-204 [auth A-318]MET:A-230 [auth A-344]HIS:A-233 [auth A-347]ARG:A-235 [auth A-349] | EC: 2.4.1.38 (PDB Primary Data) |
