Proteinâ??protein interaction inhibitor tackles drug resistance Nature.com NMR spectroscopy was then used to determine the mechanism of action of the most potent compound, termed iKIX1. The high-resolution structure showed that iKIX1 binds to the three-helix hydrophobic groove of the KIX domain of Gal11A, engaging the same ...

Abstract
Solution-state NMR has been widely applied to determine the three-dimensional structure, dynamics, and molecular interactions of proteins. The designs of experiments used in protein NMR differ from those used for small-molecule NMR, primarily because the information available prior to an experiment, such as molecular mass and knowledge of the primary structure, is...

We showed previously that the interaction of heat-shock protein 70 (Hsp70)â??Hsp90-organizing protein (HOP, aka stress-inducible phosphoprotein 1, STI1 or STIP1) with cellular prion protein (PrPC) leads to the activation of signaling pathways that ...

Accuracy and precision of proteinâ??ligand interaction kinetics determined from chemical shift titrations
Abstract NMR-monitored chemical shift titrations for the study of weak proteinâ??ligand interactions represent a rich source of information regarding thermodynamic parameters such as dissociation constants (K D ) in the micro- to millimolar range, populations for the free and ligand-bound states, and the kinetics of interconversion between states, which are typically within the fast exchange regime on the NMR timescale. We recently developed two chemical shift titration methods...

Authors: Nissler L, Gebhardt R, Berger S
Flavonoids are well known to inhibit the function of the multi-drug-resistance (mdr) transporter by interacting with their ATP binding domains. The precise orientation of these molecules inside the ATP binding pocket is still unclear. We applied the saturation transfer...

Spectrochim Acta A Mol Biomol Spectrosc. 1999 Aug;55A(9):1897-901
Authors: Luo RS, Liu ML, Mao XA
In this work, NMR diffusion and relaxation measurements are applied to the study of the interaction between the anti-inflammatory drug salicylate and the human serum albumin (HSA) in solutions. The self-diffusion coefficients and the spin-lattice relaxation rates of salicylate are measured as a function...
