Biotin chemistry
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 ...
