WebMar 12, 2024 · Figure 1. biotin labeled antibody binds with streptavidin or avidin (four binding site available, only one is shown to binding to biotin). Biotinylation Chemistry. For biotinylation chemistry, the most common reactions involve amines with biotin-NHS ester and click chemistry of azide with an alkyne (e.g. DBCO), as shown in Figure 2. Figure 2. WebBiotin’s biggest lesson is the importance of nonclassical H-bonds in protein–ligand complexes. Most of biotin’s affinity stems from its flexible valeric acid side chain that forms CH−π, CH–O, and classical H-bonds with the lipophilic region of the binding pocket. Biotin also utilizes an oxyanion hole, a sulfur-centered H-bond, and ...
