WebMay 4, 2024 · Here we describe a method of in vivo biotinylation of proteins during expression in E. coli, by tagging the protein with the short biotin acceptor peptide sequence, Avi tag, and co-expression of the E. coli biotin ligase (BirA) resulting in precise biotinylation of a specific lysine residue in the tag. Key words. Biotinylation; BirA; Avi-tag WebThe Biotin Ligase tag is described as the minimal peptide sequence that serves as a the substrate for the E. coli biotin holoenzyme synthetase, BirA. In the presence of active BirA, the biotin ligase tag (also known as the biotin acceptor peptide) becomes biotinylated, allowing for detection or purification with streptavidin. 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 … See more The non-covalent bond formed between biotin and avidin or streptavidin has a binding affinity that is higher than most antigen and antibody bonds and approaches the … See more • Hermanson, G.T. Bioconjugate Techniques. Academic Press ISBN 0-12-342336-8 • Overview of Biotinylation - Includes additional information and figures of reactive groups, biotin and linker regions. See more Purification The biotin tag can be used in affinity chromatography together with a column that has avidin (or streptavidin or neutravidin) bound to it, which is the natural ligand for biotin. However, harsh conditions (e.g., 6M GuHCl at pH 1.5) … 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 much that the biotin interferes with the function of the molecule.
