The rates of hydrogen exchange were measured in a ''physiological'' denatured state of staphylococcal nuclease using a NMR magnetization transfer experiment suitable for the measurement of exchange rates faster than 0.5 s 21 . The results are compared with predicted exchange rates (k ex ) for the ra
1H NMR spin-lattice relaxation times (T1) of the N-CH3 proton resonances of phosphocreatine (PCr) and creatine (Cr) in water solutions were obtained using the 1,3,3,1 pulse sequence. These T1 values were equivalent to those obtained in D2O and water using either the conventional inversion-recovery e
The ionization characteristics of the hydrogen-bonded His 12 AT1 proton observed to titrate between 11 to 13 ppm in the nnir spectrum of ribonuclease A in He0 solution are compared with the ionization characteristics of the four histidine CZ protons in the enzyme. Comparison of the pK,'s of the enzy
## Abstract The solution conformation of Ξ²βDβO^2^,2β²βcyclouridine has been determined at 27 and 88Β°C in D~2~O by proton magnetic resonance spectroscopy. The conformation is described in terms of a fixed __syn__βlike sugarβbase torsional angle, a type S furanose ring conformation (similar to 2β²β__en
