Methyl-NMR enables atomic-resolution studies of structure and dynamics of large proteins in solution. However, resonance assignment remains challenging. The problem is to combine existing structural informational with sparse distance restraints and search for the most compatible assignment among the permutations.

Biomolecular NMR: Isotope Labeling Methods for Protein Dynamics Studies

We presents an informational article concerning biomolecular NMR and the use of Isotope Labeling Methods for Protein Dynamics Studies.

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.
