Glycoproteins on cell surfaces play important roles in biological processes, including cell-cell interaction/signaling, immune response, and cell differentiation. Given the diversity of the structure of glycans, labeling and imaging of selected glycoproteins are challenging, although several promising strategies have been developed recently. Here, we design(More)
Catalyst-mediated protein modification is a powerful approach for the imaging and engineering of natural proteins. We have previously developed affinity-guided 4-dimethylaminopyridine (AGD) chemistry as an efficient protein modification method using a catalytic acyl transfer reaction. However, because of the high electrophilicity of the thioester acyl donor(More)
