Strain-promoted azide−alkyne cycloaddition
WebThe ability to reconstitute natural glycosylation pathways or prototype entirely new ones from scratch is hampered by the limited availability of functional glycoenzymes, plenty of the is pipe proteins that fail to express in xenogeneic hosts. Here, we explain a strategy for topologically converting membrane-bound glycosyltransferases (GTs) into water soluble … WebSeveral azide-derivatized and fluorescently-labeled peptides were immobilized on azadibenzocyclooctyne (ADIBO)-activated slide surfaces via a strain-promoted alkyne-azide cycloaddition (SPAAC) reaction revealing excellent immobilization kinetics, good spot homogeneities and reproducible fluorescence signal intensities.
