CING (biomolecular NMR structure)



In biomolecular structure, CING stands for the Common Interface for NMR structure Generation and is known for structure and NMR data validation.

NMR spectroscopy provides diverse data on the solution structure of biomolecules. CING combines many external programs and internalized algorithms to direct an author of a new structure or a biochemist interested in an existing structure to regions of the molecule that might be problematic in relation to the experimental data.

The source code is maintained open to the public at Google Code. There is a secure web interface iCing available for new data.

Applications

 * 9000+ validation reports for existing Protein Data Bank structures in NRG-CING.
 * CING has been applied to automatic predictions in the CASD-NMR experiment with results available at CASD-NMR.

Validated NMR data

 * Protein or Nucleic acid structure together called Biomolecular structure
 * Chemical shift
 * (Nuclear Overhauser effect) Distance restraint
 * Dihedral angle restraint
 * RDC or Residual dipolar coupling restraint
 * NMR (cross-)peak
