[Hypotheses about the spatial organization of glycoproteins]

The estimation of the secondary structure of the protein moiety of some glycoproteins whose sequential structure is known was carried out by using the two predictive methods of Lim and Chou and Fasman. Both results - which are in excellent agreement - allow us to propose a model concerning the spatial organization of glycoproteins studied: one can claim that beta-turns and unordered regions situated outside the protein moiety play an important role concerning the linkage of the glycan chains.
