Selective Protonation of Methyl Groups in Highly Deuterated Proteins

Sigma-Aldrich presents an article about the selective protonation of methyl groups in highly deuterated proteins. In which the structural NMR studies of small proteins, a maximum number of proton chemical shifts are usually assigned and NOEs connecting large numbers of sites are subsequently quantified in terms of distance restraints that are then used to obtain an ensemble of structures.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
