Default An introduction to NMR-based approaches for measuring protein dynamics.

An introduction to NMR-based approaches for measuring protein dynamics.

An introduction to NMR-based approaches for measuring protein dynamics.

Biochim Biophys Acta. 2010 Nov 5;

Authors: Kleckner IR, Foster MP

Proteins are inherently flexible at ambient temperature. At equilibrium, they are characterized by a set of conformations that undergo continuous exchange within a hierarchy of spatial and temporal scales ranging from nanometers to micrometers and femtoseconds to hours. Dynamic properties of proteins are essential for describing the structural bases of their biological functions including catalysis, binding, regulation and cellular structure. Nuclear magnetic resonance (NMR) spectroscopy represents a powerful technique for measuring these essential features of proteins. Here we provide an introduction to NMR-based approaches for studying protein dynamics, highlighting eight distinct methods with recent examples, contextualized within a common experimental and analytical framework. The selected methods are (1) Real-time NMR, (2) Exchange spectroscopy, (3) Lineshape analysis, (4) CPMG relaxation dispersion, (5) Rotating frame relaxation dispersion, (6) Nuclear spin relaxation, (7) Residual dipolar coupling, (8) Paramagnetic relaxation enhancement.

Measuring 1HN temperature coefficients in invisible protein states by relaxation dispersion NMR spectroscopy
Measuring 1HN temperature coefficients in invisible protein states by relaxation dispersion NMR spectroscopy Abstract A method based on the Carr-Purcell-Meiboom-Gill relaxation dispersion experiment is presented for measuring the temperature coefficients of amide proton chemical shifts of low populated ‚??invisible‚?? protein states that exchange with a ‚??visible‚?? ground state on the millisecond time-scale. The utility of the approach is demonstrated with an application to an I58D mutant of the Pfl6 Cro protein that undergoes exchange between the native, folded state and a cold...
