Correlation between 15N NMR chemical shifts in proteins and secondary structure.
An empirical correlation between the peptide 15N chemical shift, delta 15Ni, and the backbone torsion angles phi i, psi i-1 is reported. By using two-dimensional shielding surfaces delta (phi i, psi i-1), it is possible in many cases to make reasonably accurate predictions of 15N chemical shifts for a given structure. On average, the rms error between experiment and prediction is about 3.5 ppm....
متن کاملAn Empirical Correlation between Amide Deuterium Isotope Effects on 13CR Chemical Shifts and Protein Backbone Conformation
Three-dimensional, triple resonance NMR techniques are described for measurement of two-bond (intraresidual) and three-bond (sequential) amide deuterium isotope effects on 13CR chemical shifts. Measurements were carried out for uniformly 15N and 13C labeled human ubiquitin equilibrated in a 50% H2O/50% D2O mixed solvent. The three-bond isotope shift, 3∆CR(ND), ranges from about 10-50 ppb, and, ...
متن کاملAn evaluation of chemical shift index-based secondary structure determination in proteins: influence of random coil chemical shifts.
Random coil chemical shifts are commonly used to detect protein secondary structural elements in chemical shift index (CSI) calculations. Though this technique is widely used and seems reliable for folded proteins, the choice of reference random coil chemical shift values can significantly alter the outcome of secondary structure estimation. In order to evaluate these effects, we present a comp...
متن کاملCSI 3.0: a web server for identifying secondary and super-secondary structure in proteins using NMR chemical shifts
The Chemical Shift Index or CSI 3.0 (http://csi3.wishartlab.com) is a web server designed to accurately identify the location of secondary and super-secondary structures in protein chains using only nuclear magnetic resonance (NMR) backbone chemical shifts and their corresponding protein sequence data. Unlike earlier versions of CSI, which only identified three types of secondary structure (hel...
متن کاملStructure-based prediction of methyl chemical shifts in proteins.
Protein methyl groups have recently been the subject of much attention in NMR spectroscopy because of the opportunities that they provide to obtain information about the structure and dynamics of proteins and protein complexes. With the advent of selective labeling schemes, methyl groups are particularly interesting in the context of chemical shift based protein structure determination, an appr...
