A survey, primarily based on work in the authors' laboratory during the last 10 years, is provided of recent developments in NMR studies of exchange processes involving protein-ligand and protein-protein interactions. We start with a brief overview of the theoretical background of Dark state Exchange Saturation Transfer (DEST) and lifetime line-broadening (?R(2)) NMR methodology. Some limitations of the DEST/?R(2) methodology in applications to molecular systems with intermediate molecular...
[NMR paper] Investigation of protein-ligand complexes by ligand-based NMR methods
Investigation of protein-ligand complexes by ligand-based NMR methods
Molecular recognition is at the base of all biological events and its knowledge at atomic level is pivotal in the development of new drug design approaches. NMR spectroscopy is one of the most widely used technique to detect and characterize transient ligand-receptor interactions in solution. In particular, ligand-based NMR approaches, including NOE-based NMR techniques, diffusion experiments and relaxation methods, are excellent tools to investigate how ligands interact with their receptors....

Exploring weak, transient protein-protein interactions in crowded in vivo environments by in-cell NMR spectroscopy.
Biochemistry. 2011 Sep 26;
Authors: Wang Q, Zhuravleva A, Gierasch LM
Abstract
Biology relies on functional interplay of proteins in the crowded and heterogeneous environment inside cells, and functional protein interactions are often weak and transient. Thus, methods are needed that preserve these interactions...
