An automated framework for high-throughput predictions of NMR chemical shifts within liquid solutions

H Chemical Shifts in NMR

Fast and accurate predictions of protein NMR chemical shifts from interatomic distances.

We present a method, CamShift, for the rapid and accurate prediction of NMR chemical shifts from protein structures. The calculations performed by CamShift are based on an approximate expression of the chemical shifts in terms of polynomial functions of interatomic distances. Since these functions are very fast to compute and readily differentiable, the CamShift approach can be utilized in stan...

Substituent effects on 61Ni NMR chemical shifts.

(61)Ni chemical shifts of Ni(all-trans-cdt)L (cdt = cyclododecatriene, L = none, CO, PMe(3)), Ni(CO)(4), Ni(C(2)H(4))(2)(PMe(3)), Ni(cod)(2) (cod = cyclooctadiene) and Ni(PX(3))(4) (X = Me, F, Cl) are computed at the GIAO (gauge-including atomic orbitals), BPW91, B3LYP and BHandHLYP levels, using BP86-optimised geometries and an indirect referencing scheme. For this set of compounds, substituen...

Protein structure determination from NMR chemical shifts.

NMR spectroscopy plays a major role in the determination of the structures and dynamics of proteins and other biological macromolecules. Chemical shifts are the most readily and accurately measurable NMR parameters, and they reflect with great specificity the conformations of native and nonnative states of proteins. We show, using 11 examples of proteins representative of the major structural c...
