Very Fast Two-Dimensional NMR Spectroscopy for Real-Time Investigation of Dynamic Events in Proteins on the Time Scale of Seconds
Paul Schanda and Bernhard Brutscher
J. Am. Chem. Soc.; 2005; 127(22) pp 8014 - 8015


Abstract:

We demonstrate for different protein samples that 2D 1H-15N correlation NMR spectra can be recorded in a few seconds of acquisition time using a new band-selective optimized flip-angle short-transient heteronuclear multiple quantum coherence experiment. This has enabled us to measure fast hydrogen-deuterium exchange rate constants along the backbone of a small globular protein fragment by real-time 2D NMR.

Mathematical treatment of adiabatic fast passage pulses for the computation of nuclear spin relaxation rates in proteins with conformational exchange
Mathematical treatment of adiabatic fast passage pulses for the computation of nuclear spin relaxation rates in proteins with conformational exchange Abstract Although originally designed for broadband inversion and decoupling in NMR spectroscopy, recent methodological developments have introduced adiabatic fast passage (AFP) pulses into the field of protein dynamics. AFP pulses employ a frequency sweep, and have not only superior inversion properties with respect to offset effects, but they are also easily implemented into a pulse sequence. As magnetization is dragged from the +z to...

Using NMR to study fast dynamics in proteins: methods and applications. Related Articles Using NMR to study fast dynamics in proteins: methods and applications. Curr Opin Pharmacol. 2010 Oct 6; Authors: Sapienza PJ, Lee AL Proteins exist not as singular structures with precise coordinates, but rather as fluctuating bodies that move rapidly through an enormous number of conformational substates. These dynamics have important implications for understanding protein function and for structure-based drug design. NMR spectroscopy is particularly well...

[U. of Ottawa NMR Facility Blog] 19f - 13c hmqc
19F - 13C HMQC If one has an NMR spectrometer with hardware capable of synthesizing and amplifying the frequency of 19F from the 1H channel and a broadband NMR probe whose 1H channel can tune down to 19F, then one is able to do 19F - 13C HMQC experiments. The figure below shows an example of a 19F - 13C HMQC spectrum collected on a Bruker AVANCE 500 NMR spectrometer using a 5 mm broadband probe. The fluorine spectrum is plotted on the top and the 13C spectrum is plotted on the side. The panel on the left shows the spectrum optimized for one-bond coupling, while that on the right shows the...
