TROSY-selected ZZ-exchange experiment for characterizing slow chemical exchange in large proteins
TROSY-selected ZZ-exchange experiment for characterizing slow chemical exchange in large proteins
Abstract A TROSY-selected ZZ-exchange experiment is described for measuring slow chemical exchange rates by monitoring the TROSY component of 15N longitudinal magnetization. Application of the proposed pulse sequence to the cadherin 8 N-terminal extracelluar domain demonstrates that enhanced sensitivity is obtained, compared to a previously described TROSY-detected ZZ-exchange sequence (Sahu et al. J Am Chem Soc 129: 13232â??13237, 2007), by preserving the TROSY effect during the mixing...

J Mol Graph Model. 2001;19(1):3-12
Authors: Bracken C
The flexibility and dynamics of proteins directly influence the processes of protein folding, recognition, and function. NMR spin relaxation methods are used to assess the dynamics and mobility of proteins, for fast ps and ns motions as well as slower microsecond and ms events. The degree of protein...

Scientist develops new methods for characterising proteins
Using a combination of high-powered computers and advanced experimental magnetic resonance data, a Florida State University biophysical chemist has developed techniques that improve the way scientists can study and predict the structure and dynamics of proteins found in the human body.

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...

Established NMR methods are increasingly being applied to the non-native states of proteins. For small denatured proteins, full assignment of proton, 15N and 13C resonances is often straightforward. Sensitive methods exist...
