Simultaneous single-structure and bundle representation of protein NMR structures in torsion angle space
Simultaneous single-structure and bundle representation of protein NMR structures in torsion angle space
Abstract A method is introduced to represent an ensemble of conformers of a protein by a single structure in torsion angle space that lies closest to the averaged Cartesian coordinates while maintaining perfect covalent geometry and on average equal steric quality and an equally good fit to the experimental (e.g. NMR) data as the individual conformers of the ensemble. The single representative â??regmean structureâ?? is obtained by simulated annealing in torsion angle space with the...

AssignFit is a computer program developed within the XPLOR-NIH package for the assignment of dipolar coupling (DC) and chemical shift anisotropy (CSA) restraints derived from the solid-state NMR spectra of protein samples with uniaxial order. The method is based on minimizing the difference between...

Protein side-chain resonance assignment and NOE assignment using RDC-defined backbones without TOCSY data
Protein side-chain resonance assignment and NOE assignment using RDC-defined backbones without TOCSY data
Abstract One bottleneck in NMR structure determination lies in the laborious and time-consuming process of side-chain resonance and NOE assignments. Compared to the well-studied backbone resonance assignment problem, automated side-chain resonance and NOE assignments are relatively less explored. Most NOE assignment algorithms require nearly complete side-chain resonance assignments from a series of through-bond experiments such as HCCH-TOCSY or HCCCONH. Unfortunately, these TOCSY...

A novel strategy for NMR resonance assignment and protein structure determination
A novel strategy for NMR resonance assignment and protein structure determination
Abstract The quality of protein structures determined by nuclear magnetic resonance (NMR) spectroscopy is contingent on the number and quality of experimentally-derived resonance assignments, distance and angular restraints. Two key features of protein NMR data have posed challenges for the routine and automated structure determination of small to medium sized proteins; (1) spectral resolution â?? especially of crowded nuclear Overhauser effect spectroscopy (NOESY) spectra, and (2) the reliance on a...
