The unique interaction between the oligosaccharide chains have different applications. First, it aids in quality control by identifying misfolded proteins. The oligosaccharide chains also change the solubility and polarity of the proteins that they are bonded to. For example, if the oligosaccharide chains are negatively charged, with enough density around the protein, they can repulse proteolytic enzymes away from the bonded protein. The diversity in interactions lends it… Web29 de abr. de 2024 · There are many glycans in virus surface glycoproteins, and they affect the virulence of the virus by regulating the binding of the virus to host receptors, covering up antigenic sites, or stimulating host immune responses to affect virulence ( 71 ). These glycans play different roles in the virulence of the virus.
