[Question from NMRWiki Q&A forum] Chemical exchange of Tyr residues - what information can be found about dynamics?
Chemical exchange of Tyr residues - what information can be found about dynamics?
I have an aromatic spectrum of Tyr residues in p53 DNA binding domain. No peaks are seen for Tyr-205 at high temp, but as temp decreases 4 peaks are shown. Tyr-163 and Tyr-236 show two peak each at high temps. How come there aren't 4 peaks? The dynamic processes are said to occur on different time scales. What is the interpretation of this information? How is the core domain of p53 influenced by this? Thanks for your help!

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...
