Proteins with covalently attached sugar units, either bonded via the OH group of serine or threonine (O-glycosylated) or through the amide NH2 of asparagine (N-glycosylated) Includes most secreted proteins (serum albumin is the major exception) and proteins exposed at the outer surface of the plasma membrane Sugar residues found include: - mannose, N-acetyl glucosamine, N-acetyl galactosamine, galactose, fucose and sialic acid
A protein that carries attatched to it some chains of sugars (glycans) PrP carries two of these chains and it has been suggested that it is different chains that actually separate the strains of TSEs
a small unit made up of a sugar and a protein molecule, often part of a cell's membrane Glycoproteins make up the envelope of HIV (e g , gp120, gp160 [numbers denote molecular weight])
A molecule that is composed of a protein molecule linked to a carbohydrate molecule
A category of macromolecules in which a single polysaccharide or group of polysaccharides are combined with a protein
A protein that carries attached to it some chains of sugars (glycans) PrP carries two of these chains and it has been suggested that it is different chains that actually separate the strains of TSEs
A conjugated protein in which the nonprotein group is a carbohydrate (i e , a sugar molecule); also called glucoprotein
