Folding Trp-cage to NMR resolution native structure using a coarse-grained protein model.

Related Articles Folding Trp-cage to NMR resolution native structure using a coarse-grained protein model.

Biophys J. 2005 Jan;88(1):147-55

Authors: Ding F, Buldyrev SV, Dokholyan NV


We develop a coarse-grained protein model with a simplified amino acid interaction potential. Using this model, we perform discrete molecular dynamics folding simulations of a small 20-residue protein--Trp-cage--from a fully extended conformation. We demonstrate the ability of the Trp-cage model to consistently reach conformations within 2-angstroms backbone root-mean-square distance from the corresponding NMR structures. The minimum root-mean-square distance of Trp-cage conformations in simulations can be

Structure-based protein NMR assignments using native structural ensembles
Structure-based protein NMR assignments using native structural ensembles Mehmet Serkan Apaydın, Vincent Conitzer and Bruce Randall Donald Journal of Biomolecular NMR; 2008; 40(4); pp 263-276 Abstract: An important step in NMR protein structure determination is the assignment of resonances and NOEs to corresponding nuclei. Structure-based assignment (SBA) uses a model structure (“template”) for the target protein to expedite this process. Nuclear vector replacement (NVR) is an SBA framework that combines multiple sources of NMR data (chemical shifts, RDCs, sparse NOEs, amide exchange...
