Chicken avidin-related proteins show altered biotin-binding and physico-chemical properties as compared with avidin.
Chicken avidin and bacterial streptavidin are proteins familiar from their use in various (strept)avidin-biotin technological applications. Avidin binds the vitamin biotin with the highest affinity known for non-covalent interactions found in nature. The gene encoding avidin (AVD) has homologues in chicken, named avidin-related genes (AVRs). In the present study we used the AVR genes to produce...
متن کاملAvidin related protein 2 shows unique structural and functional features among the avidin protein family
BACKGROUND The chicken avidin gene family consists of avidin and several avidin related genes (AVRs). Of these gene products, avidin is the best characterized and is known for its extremely high affinity for D-biotin, a property that is utilized in numerous modern life science applications. Recently, the AVR genes have been expressed as recombinant proteins, which have shown different biotin-bi...
متن کاملUnbinding biotin from avidin
Atomic force microscopy of single molecules, steered molecular dynamics and the theory of stochastic processes have established a new field that investigates mechanical functions of proteins, such as ligand–receptor binding/unbinding and elasticity of muscle proteins during stretching. The combination of these methods yields information on the energy landscape that controls mechanical function ...
متن کاملThree-dimensional structures of avidin and the avidin-biotin complex.
The crystal structures of a deglycosylated form of the egg-white glycoprotein avidin and of its complex with biotin have been determined to 2.6 and 3.0 A, respectively. The structures reveal the amino acid residues critical for stabilization of the tetrameric assembly and for the exceptionally tight binding of biotin. Each monomer is an eight-stranded antiparallel beta-barrel, remarkably simila...
متن کاملProtein assemblies by site-specific avidin-biotin interactions.
Exploiting self-assembly systems with biological building blocks is of significant interest in the fabrication of advanced biomaterials. We assessed the potential use of site-specific ligand labeling of protein building blocks in designing functional protein self-assemblies by combining site-specifically biotinylated bacterial alkaline phosphatase (as a bidentate or tetradentate ligand unit) an...
