Rous sarcoma virus glycoproteins contain hybrid-type oligosaccharides.

摘要

Examination of [3H]mannose-labeled glycopeptides from Prague C Rous sarcoma virus gp85 with gel filtration and sequential glycosidase digestions demonstrated the presence of hybrid-type asparaginyl-oligosaccharides. The major hybrid species had an oligomannosyl core (Man5GlcNAc2-ASN) characteristic of neutral structures, plus "branch" sugars (NeuNAc-Gal-GlcNAc-) characteristic of complex, acidic structures.
