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. WebThe bond formation between biotin and avidin is very rapid, and once formed, it is unaffected by extremes in pH, temperature, organic solvents and other denaturing …
