Proximity labeling relies on a labeling enzyme that can biotinylate nearby biomolecules promiscuously. Biotin labeling can be achieved through several different methods, depending on the species of labeling enzyme. • BioID, also known as BirA*, is a mutant E. coli biotin ligase that catalyzes the activation of biotin by ATP. The activated biotin is short-lived and thus can only diffuse to a region proximal to BioID. L… WebNov 24, 2014 · Then live cells are treated for 1 min with H 2 O 2 in the presence of biotin-phenol.
