Here we show that AMPs can be modified with a high … WebJan 9, 2024 · We found that the WYKYW‐tag binds the glycan moiety of the caveolar receptor GM1 with high affinity. The lack of strong interactions with GM3 and asialo‐GM1 indicated selective behavior. We concluded that both the sialyl group and the terminal N‐Ac‐digalactoside in GM1 are essential structural features for the low nanomolar binding.
