The study was designed to understand the effect of orotic acid (OA) on the expression of beta 1,4-galactosyltransferase (GalTase), an enzyme involved in the transfer of galactose from UDP-galactose to a non-reducing terminal N-acetylglucosamine of a

The activity of N-acetylglucosaminyltransferase III, which adds a "bisecting" GlcNAc in beta 1,4 linkage to the beta-linked Man of the core of Asn-linked oligosaccharides (Narasimhan, S. (1982) J. Biol. Chem. 257, 10235-10242), was determined in hepa

The ricin-resistant mutant baby hamster kidney (BHK) cell line RICR21 is unable to make the sialylated bi- or triantennary complexN-glycans found in wild type cells and accumulates instead non-bisected hybrid structures containing three Man residues

The asparagine-linked oligosaccharide structures of chronic lymphocytic leukemia cells (CLL) were studied by sequential lectin affinity chromatography. Glycopeptides were isolated from a Concanavalin A (ConA)-binding glycoprotein fraction prepared fr

The effect of a "bisecting" 2-acetamido-2-deoxy-beta-D-glucopyranosyl group, linked (1----4) to the beta-D-mannopyranosyl group of asparagine-linked complex and hybrid oligosaccharides, on the binding of [14C]acetylated glycopeptides to columns of im

Twelve 14C-acetylated glycopeptides have been subjected to affinity chromatography on concanavalin A (Con A) – Sepharose at pH 7.5. The elution profiles could be classified into four distinct patterns. The first pattern showed no retardation of gly

A GDP- l -fucose:glycoprotein fucosyltransferase which transfers l -fucose to terminal β-N-acetyl- d -glucosaminyl residues of sialidase-, β-galactosidase-treated α1-acid glycoprotein and a CMP-sialic acid:glycoprotein sialyltransferase acting on

One of the most striking features of N - and O -glycosyl oligosaccharides and of lipid-linked oligosaccharides is the high degree of branching of these complex structures. Both proteins and nucleic acids are essentially linear structures and are synt

Bovine milk UDPgalactose:N-acetylglucosamine beta-4-galactosyltransferase has been used to investigate the effect of a bisecting GlcNAc residue (linked beta 1,4 to the beta-linked mannose of the trimannosyl core of asparagine-linked complex oligosacc

Many mammalian and avian complex carbohydrates (glycoproteins and glycolipids) have highly branched oligosaccharides. Although the function of complex carbohydrates is not known, there is evidence to suggest that oligosaccharide branching may be an i
