Abstract
BACKGROUND: To understand the mechanisms related to the 'dynamical ordering' of macromolecules and biological systems, it is crucial to monitor, in detail, molecular interactions and their dynamics across multiple timescales. Solution nuclear magnetic resonance (NMR) spectroscopy is an ideal tool that can investigate biophysical events at the atomic level, in near-physiological buffer solutions, or even inside cells. Scope of Review In the past several decades, progress in solution NMR has significantly contributed to the elucidation of three-dimensional structures, the understanding of conformational motions, and the underlying thermodynamic and kinetic properties of biomacromolecules. This review discusses recent methodological development of NMR, their applications and some of the remaining challenges. Major Conclusions Although a major drawback of NMR is its difficulty in studying the dynamical ordering of larger biomolecular systems, current technologies have achieved considerable success in the structural analysis of substantially large proteins and biomolecular complexes over 1 MDa and have characterised a wide range of timescales across which biomolecular motion exists. While NMR is well suited to obtain local structure information in detail, it contributes valuable and unique information within hybrid approaches that combine complementary methodologies, including solution scattering and microscopic techniques. General Significance For living systems, the dynamic assembly and disassembly of macromolecular complexes is of utmost importance for cellular homeostasis and, if dysregulated, implied in human disease. It is thus instructive for the advancement of the study of the dynamical ordering to discuss the potential possibilities of solution NMR spectroscopy and its applications. This article is part of a Special Issue entitled "Biophysical Exploration of Dynamical Ordering of Biomolecular Systems" edited by Dr. Koichi Kato.

[Question from NMRWiki Q&A forum] Varian FIDs ordering: Inner and outer loop in the sequence(Rance-Kay & States)?
Varian FIDs ordering: Inner and outer loop in the sequence(Rance-Kay & States)? Dear all, I am new to NMR and I have difficulty understanding the ordering of FIDs, e.g. if an experiment uses both Rance-Kay and States, there will be loops(outer/inner) which need to be taken care during data processing. I don't completely understand how FIDs(indirect dimension) are stored and in what order. In a pulse sequnece, what an inner or outer loop corresponds to? Check if somebody has answered this question on NMRWiki QA forum
