Beta-D-O-glucosylation produces a remarkable effect on the peptide backbone of the model peptides derived from serine and threonine. Consequently, this type of glycosylation is responsible for the experimentally observed shift from extended conformations (model peptides) towards the folded conformations (model glycopeptides). The conclusion has been solidly assessed by a combined NMR/MD protocol. Interestingly
