Abstract
Conformational Exchange: Small GTPases, such as Ras and Rheb, exchange between major and minor conformers when bound to GTP, with different functional properties for each state. Two-dimensional (15) N CEST NMR spectroscopy is used to quantify the exchange parameters for both Ras and Rheb complexed with physiological GTP and the analogues GTP?S and GppNHp.

Characterization of slow conformational dynamics in solids: dipolar CODEX Characterization of slow conformational dynamics in solids: dipolar CODEX Abstract A solid state NMR experiment is introduced for probing relatively slow conformational exchange, based on dephasing and refocusing dipolar couplings. The method is closely related to the previously described Centerband-Only Detection of Exchange or CODEX experiment. The use of dipolar couplings for this application is advantageous because their values are known a priori from molecular structures, and their orientations and reorientations relate in a simple way to molecular geometry and motion. Furthermore...	nmrlearner	Journal club	0	01-09-2011 12:46 PM
