Biotin and lysine
In biochemistry, biotinylation is the process of covalently attaching biotin to a protein, nucleic acid or other molecule. Biotinylation is rapid, specific and is unlikely to disturb the natural function of the molecule due to the small size of biotin (MW = 244.31 g/mol). Biotin binds to streptavidin and avidin with an … See more 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., … See more Reaction conditions for biotinylation are chosen so that the target molecule (e.g., an antibody) is labeled with sufficient biotin molecules to purify or detect the molecule, but not so … See more • Hermanson, G.T.

WebBiotin-binding affinity can be impaired by chemical labeling of streptavidin, such as with amine-reactive fluorophores; flavidin is a streptavidin mutant without lysine side-chains, which retains good biotin binding characteristics after such fluorescent dye labeling where the dye couples to the amino terminus. Uses in biotechnology WebJan 11, 2024 · Biotin (also called vitamin H or B7) is an essential cofactor of biotin-dependent enzymes including carboxylases, decarboxylases and transcarboxylases, all of which participate in various aspects of intermediary metabolism, including gluconeogenesis, fatty acid synthesis and amino acid metabolism (Walsh 2006, Tong 2013 ).
