title: In vivo enzymatic protein biotinylation.
abstract: Biotin is biologically active only when protein-bound and is covalently attached to a class of important metabolic enzymes, the biotin carboxylases and decarboxylases. Biotinylation is a relatively rare modification, with between one and five biotinylated protein species found in different organisms. We discuss the mechanism and structures involved in this extraordinarily specific protein modification and its exploitation in tagging recombinant proteins.
