different effect on the backbone of the peptide derived from Thr and MeSer. In the former, the β-O-glycosylation is responsible for the experimentally observed shift from extended conformations (peptide) to folded ones (glycopeptide). In contrast, the β-O-glycosylation of the MeSer-containing peptide, which clearly shows two main conformations in aqueous solution [extended ones (70%) and β-turn (30%)]
