Default Type I and II ?-turns prediction using NMR chemical shifts.

Type I and II ?-turns prediction using NMR chemical shifts.

Related Articles Type I and II ?-turns prediction using NMR chemical shifts.

J Biomol NMR. 2014 May 17;

Authors: Wang CC, Lai WC, Chuang WJ


Abstract
A method for predicting type I and II ?-turns using nuclear magnetic resonance (NMR) chemical shifts is proposed. Isolated ?-turn chemical-shift data were collected from 1,798 protein chains. One-dimensional statistical analyses on chemical-shift data of three classes ?-turn (type I, II, and VIII) showed different distributions at four positions, (i) to (i*+*3). Considering the central two residues of type I ?-turns, the mean values of C?, C?, HN, and NH chemical shifts were generally (i*+*1)*>*(i*+*2). The mean values of C? and H? chemical shifts were (i*+*1)*

Structure-based prediction of methyl chemical shifts in proteins
Structure-based prediction of methyl chemical shifts in proteins Abstract 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 approach that to date has exploited primarily the mapping between protein structures and backbone chemical shifts. In order to...

4D prediction of protein 1H chemical shifts
4D prediction of protein 1H chemical shifts Abstract A 4D approach for protein 1H chemical shift prediction was explored. The 4th dimension is the molecular flexibility, mapped using molecular dynamics simulations. The chemical shifts were predicted with a principal component model based on atom coordinates from a database of 40 protein structures. When compared to the corresponding non-dynamic (3D) model, the 4th dimension improved prediction by 6â??7%. The prediction method achieved RMS errors of 0.29 and 0.50 ppm for Hα and HN shifts, respectively. However, for individual proteins...

Prediction of Xaa-Pro peptide bond conformation from sequence and chemical shifts
Abstract We present a program, named Promega, to predict the Xaa-Pro peptide bond conformation on the basis of backbone chemical shifts and the amino acid sequence. Using a chemical shift database of proteins of known structure together with the PDB-extracted amino acid preference of cis Xaa-Pro peptide bonds, a cis/trans probability score is calculated from the backbone and 13Cβ chemical shifts of the proline and its neighboring residues. For an arbitrary number of input chemical shifts, which may include Pro-13Cγ, Promega calculates the statistical probability that a Xaa-Pro peptide bond...
