Novel forms of protein glycosylation.
A large number of new glycans, derived from glycoproteins, has been characterized in the past few years. O-linked fucose was found in epidermal growth factor-like domains of several proteins. For the N-linked glycans of Helix pomatia hemocyanin, novel types of antennae were identified. The positions of noncarbohydrate substituents were established in N-glycans. C-mannosylation of a tryptophan residue was discovered in human ribonuclease 2 and is the first example of C-glycosylation in glycoproteins.
