Articles
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.
