일반 설명
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.
애플리케이션
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
생화학적/생리학적 작용
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.
물리적 형태
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

The extremely tight binding between biotin and avidin or streptavidin makes labeling proteins with biotin a useful tool for many applications. BirA is the Escherichia coli biotin ligase that site-specifically biotinylates a lysine side chain within a 15-amino acid acceptor

ATP-powered unfoldases containing D1 and D2 AAA+ rings play important roles in protein homeostasis, but uncertainty about the function of each ring remains. Here we use single-molecule optical tweezers to assay mechanical unfolding and translocation by a variant of the
