N-linked sugar chain rings
WebAn endo-type glycosidase (endoglycosidase) acts on glycosidic bonds (1) at the inner region of the sugar chain or (2) at the linkage region between the core protein (or core lipid) and … DNA molecules contain 5-membered carbon rings called riboses that are directly attached to two phosphate groups and a nucleobase that contains amino groups. The nitrogen atoms from the amino group in the nucleotides are covalently linked to the anomeric carbon of the ribose sugar structure through an N-glycosidic bond. Occasionally, the nucleobases attached to the ribose undergo deamination, alkylation, or oxidation which results in cytotoxic lesions along the DNA ba…

WebDNA molecules contain 5-membered carbon rings called riboses that are directly attached to two phosphate groups and a nucleobase that contains amino groups. The nitrogen atoms from the amino group in the nucleotides are covalently linked to the anomeric carbon of the ribose sugar structure through an N-glycosidic bond. WebBoth subunits of hCG contain two N-linked sugar chains (Figure 12). 73,74 The β-subunit of hCG contains four O-linked sugar chains in addition. 74 These O-linked sugar chains are clustered from Ser121 to Ser138, probably by the substrate specificity of ppGaNTase described in Section 1.02.2.1.
WebFive and six-membered rings are favored over other ring sizes because of their low angle and eclipsing strain. Cyclic structures of this kind are termed furanose (five-membered) or pyranose (six-membered), reflecting the ring size relationship to the common heterocyclic compounds furan and pyran shown on the right.
