A spectroscopic assignment technique for membrane proteins reconstituted in magnetically aligned bicelles
A spectroscopic assignment technique for membrane proteins reconstituted in magnetically aligned bicelles
Abstract Oriented-sample NMR (OS-NMR) has emerged as a powerful tool for the structure determination of membrane proteins in their physiological environments. However, the traditional spectroscopic assignment method in OS NMR that uses the â??shotgunâ?? approach, though effective, is quite labor- and time-consuming as it is based on the preparation of multiple selectively labeled samples. Here we demonstrate that, by using a combination of the spin exchange under mismatched...

In this paper, a scheme for estimating frequencies and damping factors of multidimensional nuclear magnetic resonance (NMR) data is presented, multidimensional NMR data can be modeled as the sum of several multidimensional damped sinusoids. The estimated frequencies and damping factors of multidimensional NMR data...

[U. of Ottawa NMR Facility Blog] NMR and Food Chemistry - Coffee
NMR and Food Chemistry - Coffee
Many of us enjoy a hot delicious cup of coffee. Many (not including myself) will even spend a great deal of money and a great deal of their time in a long queue to get it! The coffee snobs will preach about the differences between a freshly brewed cup of java and the lowly cup of instant coffee. Is there really a difference? Spectrum A in the figure below shows the 13C CPMAS NMR spectrum of ground coffee. Among other things, the spectrum consists of resonances from the woody fibers, polysaccharide gums, tannins, alkaloids and aromatic oils. Spectrum B is the...

[NMR analysis blog] New Fast NMR technique
New Fast NMR technique
Instrument time is precious and a plethora of different fast NMR experiments are continuously being proposed in order to reduce the time required to record an NMR spectrum. Actually, money is not the only reason, there are many other factors which motivate the development of techniques to increase the speed of data collection. For example, if one wants to make real-time studies of kinetic processes or protein folding, it’s pivotal to speed up the acquisition of NMR data, in particular multidimensional spectra.
On this issue, we have just put our bit into this field...
