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.
