TL;DR: In this article, a set of 3D spectra based on a Cα-Hα detection block was developed and applied for the sequence-specific backbone and aliphatic side-chain resonance assignment using only 500 μg of sample.
Journal ArticleDOI
Backbone assignment of fully protonated solid proteins by 1H detection and ultrafast magic-angle-spinning NMR spectroscopy.

TL;DR: This approach provides assignments of the backbone 1H, 15N, 13C α, and 13CO resonances and yields information about 1H-1H proximities.
Journal ArticleDOI
Improving a Natural Enzyme Activity through Incorporation of Unnatural Amino Acids
Isaac N Ugwumba,Kiyoshi Ozawa,Zhi-Qiang Xu,Fernanda Ely,Jee Foo,Anthony J. Herlt,Christopher W. Coppin,Susan E. Brown,Matthew C. Taylor,David L. Ollis,Lewis N. Mander,Gerhard Schenk,Nicholas E. Dixon,Gottfried Otting,John G. Oakeshott,Colin J. Jackson +15 more
TL;DR: Kinetic analysis suggests that the 7-hydroxyl group of Hco contributes to an increase in the rate-limiting product release step of substrate turnover as a result of its electrostatic repulsion of the negatively charged 4-nitrophenolate product of paraoxon hydrolysis.
