Description: STAP refinement of NMR Database is based the Statistical Torsion Angles Potentials to refine the NMR structure. It stored original solution NMR structures from the Protein Data Banks and our refined structures. Currently we carried out 2,405 refined NMR structure (until Sept 20, 2011). According to several studies, some nuclear magnetic resonance (NMR) structures are of lower quality, less reliable and less suitable for structural analysis than high-resolution X-ray crystallographic structures. STAP of NMR Refinement Database is a public database of 2405 refined NMR solution structures from the Protein Data Bank (PDB). A simulated annealing protocol was employed to obtain refined structures with target potentials, including the newly developed STAP. The refined database was extensively analyzed using various quality indicators from several assessment programs to determine the nuclear Overhauser effect (NOE) completeness, Ramachandran appearance, (1)-(2) rotamer normality, various parameters for protein stability and other indicators. Most quality indicators are improved in our protocol mainly due to the inclusion of the newly developed knowledge-based potentials. This database can be used by the NMR structure community for further development of research and validation tools, structure-related studies and modelling in many fields of research.
