Density functional calculations of backbone 15N shielding tensors in beta-sheet and turn residues of protein G
Abstract We performed density functional calculations of backbone 15N shielding tensors in the regions of beta-sheet and turns of protein G. The calculations were carried out for all twenty-four beta-sheet residues and eight beta-turn residues in the protein GB3 and the results were compared with the available experimental data from solid-state and solution NMR measurements. Together with the alpha-helix data, our calculations cover 39 out of the 55 residues (or 71%) in GB3....

Density functional calculations of 15N chemical shifts in solvated dipeptides
Density functional calculations of 15N chemical shifts in solvated dipeptides
Ling Cai, David Fushman and Daniel S. Kosov
Journal of Biomolecular NMR; 2008; 41(2) pp 77 - 88
Abstract:
We performed density functional calculations to examine the effects of solvation, hydrogen bonding, backbone conformation, and the side chain on 15N chemical shielding in proteins. We used N-methylacetamide (NMA) and N-formyl-alanyl-X (with X being one of the 19 naturally occurring amino acids excluding proline) as model systems. In addition, calculations were performed for selected fragments from...
