Molecule diagrams generated from .mol files obtained from the KEGG ftp site.

Other name(s): GalT. Glycoprotein 4-beta-galactosyltransferase. Thyroid galactosyltransferase. UDP-galactose--glycoprotein galactosyltransferase.
Comments: Terminal N-acetyl-beta-D-glucosaminyl residues in polysaccharides, glycoproteins and glycopeptides can act as acceptor. High activity is shown toward such residues in branched-chain polysaccharides when these are linked by beta-1,6 links to galactose residues; lower activity toward residues linked to galactose by beta- 1,3 links. A component of ec 2.4.1.22.
