Sialic acids: XIII. A uridine diphosphate d-galactose: mucin galactosyltransferase from porcine submaxillary gland

H Schachter, EJ McGuire, S Roseman - Journal of Biological Chemistry, 1971 - ASBMB
A particulate galactosyltransferase isolated from pig submaxillary glands catalyzed the
transfer of galactose from uridine diphosphate galactose to both high and low molecular
weight derivatives of N-acetylgalactosamine (2-acetamido-2-deoxy-d-galactopyranosides).
The most effective acceptor for this enzyme was sialidase-treated ovine submaxillary mucin.
The product of this reaction was galactosyl→ N-acetylgalactosaminyl→ protein, which is an
intermediate in the biosynthesis of the more complex oligosaccharides of porcine …
