Changing employment: Receptor 1 binds β-N-acetylglucosaminyl (β-GlcNAc) up to 100 times more strongly than it does glucose. This synthetic lectin shows affinities similar to wheat germ agglutinin (WGA), a natural lectin used to bind GlcNAc. Remarkably, 1 is more selective than WGA. It favors especially the glycoside unit in glycopeptide 2, a model of the serine-O-GlcNAc posttranslational protein modification.
