Synthesis of biotin-labelled core glycans of GPI anchors and their application in the study of GPI interaction with pore-forming bacterial toxins

Abstract

A convergent strategy was developed for the first-time synthesis of biotin-labeled GPI core glycans. These GPI conjugates are useful for various biological studies showcased by their application in the scrutiny of pore-forming bacterial toxin–GPI interaction, revealing that the phosphate group at the GPI inositol 1-O-position had a significant impact on GPI–toxin binding.
