Biotin is a water-soluble vitamin that participates as a cofactor in gluconeogenesis, fatty acid synthesis and branched chain amino acid catabolism. It functions as the carboxyl carrier for biotin-dependent carboxylases. Its covalent attachment to carboxylases is catalyzed by holocarboxylase synthetase.

The thermodynamic stability of proteins is typically measured at high denaturant concentrations and then extrapolated back to zero denaturant conditions to obtain unfolding free energies under native conditions. For membrane proteins, the extrapolations are fraught with considerable uncertainty as the

A stable liposome-based time-resolved luminescence resonance energy transfer (TR-LRET) assay was developed based on the interaction of biotinylated lipids and streptavidin. Eu(3+) ion chelated to 4,4,4-trifluoro-1-(2-naphthalenyl)-1,3-butanedione and trioctylphosphine oxide was incorporated into liposomes. Acceptor-labeled streptavidin bound to biotinylated lipids of

The four last steps of biotin biosynthesis, starting from pimeloyl-CoA, are conserved among all the biotin-producing microorganisms. Two enzymes of this pathway, the 8-amino-7-oxononanoate synthase (AONS) and the 7,8-diaminopelargonic acid aminotransferase (DAPA AT) are dependent on pyridoxal-5'-phosphate (PLP). This review

Biotin serves as a covalently bound coenzyme in five human carboxylases; biotin is also attached to histones H2A, H3, and H4, although the abundance of biotinylated histones is low. Biotinylation of both carboxylases and histones is catalyzed by holocarboxylase synthetase.
