Conformational studies on phenyl thioglycosides: a remote effect on disaccharide linkage by phenyl aglycons attenuates recognition of galabiosides by a bacterial adhesin.

Phenyl S-galabiosides display altered conformational properties, as compared to phenyl O-galabiosides, characterised by a remote effect on the galabiose intersaccharidic glycoside bond by the phenyl aglycon, resulting in significantly lowered affinity for the PapG class II adhesin of uropathogenic E. coli.
