What is glycan degradation?
What is glycan degradation? The degradation of glycans is ordered and often highly specific. It involves both endo- and exoglycosidases that eventually liberate monosaccharides, sometimes with the aid of noncatalytic proteins. What is the function of glycan? Biological functions of glycans can be divided into three broad categories: (1) structural and modulatory properties, including nutrient storage and sequestration; (2) specific recognition by other molecules—most commonly, glycan-binding proteins (GBPs); and (3) molecular mimicry of host glycans (Figure 7.1). How are glycoproteins degraded? Glycoproteins are delivered to lysosomes for catabolism either by endocytosis from outside the cell or by autophagy within the...
