General description

Biotin ligase BirA (GenBank Accession No. AP012306 (3602298-3603260)) amino acids 2 – 321 (end) with His-FLAG-tag, MW = 37.1 kDa, expressed in an Escherichia coli cell expression system.

Application

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

Biochem/physiol Actions

Biotin ligase BirA controls biotin synthesis in Escherichia coli. It sends biotin to metabolism. As a homodimer, it negatively controls the biotin synthetic operon. BirA also catalyzes post-translational biotinylation, by associating with biotin acceptor protein of acetyl-coenzyme A carboxylase. It can biotinylate human histones.

Physical form

Formulated in 50 mM Tris-HCl, pH 8.0, 50 mM NaCl, 150 mM imidazole, 3 mM DTT, and 5% Glycerol.

Transcription of the Escherichia coli biotin (bio) operon is directly regulated by the biotin protein ligase BirA, the enzyme that covalently attaches biotin to its cognate acceptor proteins. Binding of BirA to the bio operator requires dimerization of the protein
