Proteins can be biotinylated chemically or enzymatically. Chemical biotinylation utilises various conjugation chemistries to yield nonspecific biotinylation of amines, carboxylates, sulfhydryls and carbohydrates (e.g., NHS-coupling gives biotinylation of any primary amines in the protein). Enzymatic biotinylation results in biotinylation of a specific lysine within a certain sequence by a bacterial biotin ligase. Most chemical biotinylation reagents consist of a reactive group attached … WebMay 31, 2024 · Biotin binds to avidin, with an astonishing free energy of binding of −20.75 kcal/mol and in ...

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. WebAdvantages of using Avidin-biotin systems. The Avidin-biotin complex is the strongest known non-covalent interaction (K d = 10 -15 M) between a protein and ligand. The bond formation between biotin and Avidin is very rapid, and once formed, is unaffected by extremes of pH, temperature, organic solvents and other denaturing agents.
