Abstract
Conformational exchange in proteins is a major determinant in protein functionality. In particular, the ?s-ms timescale is associated with enzymatic activity and interactions between biological molecules. We show here that a comprehensive data set of R1? relaxation dispersion profiles employing multiple effective fields and tilt angles can be easily obtained in perdeuterated, partly back-exchanged proteins at fast magic-angle spinning and further complemented with chemical-exchange saturation transfer NMR experiments. The approach exploits complementary sources of information and enables the extraction of multiple exchange parameters for ?s-ms timescale conformational exchange, most notably including the sign of the chemical shift differences between the ground and excited states.

Insight into the conformational stability of membrane-embedded BamA using a combined solution and solid-state NMR approach
Abstract
The β-barrel assembly machinery (BAM) is involved in folding and insertion of outer membrane proteins in Gram-negative bacteria, a process that is still poorly understood. With its 790 residues, BamA presents a challenge to current NMR methods. We utilized a â??divide and conquerâ?? approach in which we first obtained resonance assignments for BamAâ??s periplasmic POTRA domains 4 and 5 by solution NMR. Comparison of...

Solid-state NMR (SSNMR) is an invaluable tool for determining orientations of membrane proteins and peptides in lipid bilayers. Such orientational descriptions provide essential information about membrane protein functions. However, when a semi-static single conformer model is used to interpret various SSNMR observables, important dynamics information can...
