Conformational analysis by quantitative NOE measurements of the β-proton pairs across individual disulfide bonds in proteins
Conformational analysis by quantitative NOE measurements of the β-proton pairs across individual disulfide bonds in proteins
Abstract NOEs between the β-protons of cysteine residues across disulfide bonds in proteins provide direct information on the connectivities and conformations of these important cross-links, which are otherwise difficult to investigate. With conventional -proteins, however, fast spin diffusion processes mediated by strong dipolar interactions between geminal β-protons prohibit the quantitative measurements and thus the analyses of long-range NOEs across...

[U. of Ottawa NMR Facility Blog] Solid State NMR of Half Integer Quadrupolar Nuclei
Solid State NMR of Half Integer Quadrupolar Nuclei
Many students who do liquid state NMR or solid state NMR of spin I=1/2 nuclei have very little appreciation for the information content and complexity of the solid state NMR spectra of spin I = n/2 quadrupolar nuclei (n= 3, 5, 7....). In part, I think this may be due to the mathematics involved with explaining the important effects. With this post, I attempt to describe the NMR spectrum of an I = 5/2 nucleus in the soild state without resorting to mathematics. I hope that this post helps to boost the understanding and appreciation for the...
