Biotinylation-based method
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 … WebDec 2, 2024 · BioID: a promiscuous biotin ligase that can efficiently label neighboring proteins The first biotin based proximity labelling technique, BioID, was developed in 2012 in the Brian Burke Lab (Roux et al., 2012). BioID utilizes the E. coli biotin ligase, BirA*, with a site mutation (R11G).
