WebUNIT DEFINITION: One unit of BirA is defined as the amount of enzyme that catalyzes the biotinylation of 1 µmol of Avi-tagged protein (CD40L-Avi) per minute under the assay conditions, where 50% of CD40L-Avi is biotinylated in 60 min at 30 °C in the reaction buffer containing 5 mM MgCl 2, 2 mM ATP, 150 µM

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.
