WebJun 13, 2024 · The biotin–avidin as well as biotin–streptavidin interactions are among the strongest ones between molecules not relying on the formation of covalent bonds. Each protein can bind up to four biotin molecules, two for each of its facets. When bound, they therefore reside on opposing sites of the protein. 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 ...
