In vitro Biotinylation of Avitag with Enzyme

Biotin-protein ligase (EC activates biotin to form biotinyl 5' adenylate and transfers the biotin to biotin-accepting proteins. It also functions as a biotin operon repressor. This protein is encoded by the birA gene.

Other names for this enzyme include: biotin ligase; biotin operon repressor protein; birA; biotin holoenzyme synthetase; biotin-[acetyl-CoA carboxylase] synthetase.
