Default Characterization of caged compounds binding to proteins by NMR spectroscopy.

Characterization of caged compounds binding to proteins by NMR spectroscopy.

Characterization of caged compounds binding to proteins by NMR spectroscopy.

Biochem Biophys Res Commun. 2010 Aug 27;

Authors: Bandorowicz-Pikula J, Buchet R, Cañada FJ, Clémancey M, Groves P, Jiménez-Barbero J, Lancelin JM, Marcillat O, Pikula S, Sekrecka-Belniak A, Strzelecka-Kiliszek A

Photolysable caged ligands are used to investigate protein function and activity. Here, we investigate the binding properties of caged nucleotides and their photo released products to well established but evolutionary and structurally unrelated nucleotide-binding proteins, rabbit muscle creatine kinase (RMCK) and human annexin A6 (hAnxA6), using saturation transfer difference NMR spectroscopy. We detect the binding of the caged nucleotides and discuss the general implications on interpreting data collected with photolysable caged ligands using different techniques. Strategies to avoid non-specific binding of caged compound to certain proteins are also suggested.

Related Articles Preparation, characterization, and NMR spectroscopy of encapsulated proteins dissolved in low viscosity fluids. J Biomol NMR. 2003 Apr;25(4):313-23 Authors: Babu CR, Flynn PF, Wand AJ Encapsulating a protein in a reverse micelle and dissolving it in a low-viscosity solvent can lower the rotational correlation time of a protein and thereby provides a novel strategy for studying proteins in a variety of contexts. The...
