A worldwide e-Infrastructure for NMR and structural biology

NMR Tools

Format Converter

The CcpNmr FormatConverter web interface was designed to facilitate conversions between any existing NMR data formats and types. The underlying code is based on the existing CcpNmr FormatConverter code. Go to the service >>


SHIFTX2 predicts both the backbone and side chain 1H, 13C and 15N chemical shifts for proteins using their structural (PDB) coordinates as input. Go to the service >>


The antechamber suite automates the process of developing a charge distribution and assigning atom types, and partially automates the process of developing parameters for the various combinations of atom types found in a given molecule. Antechamber can automatically generate input force field parameters for most organic molecules, thereby allowing users to use AMBER, also through AMPS-NMR web portal, to refine the structure of protein-ligand adducts. Go to the service >>


PREDITOR is a program for PREDIcting φ, ψ, χ1, and ω TORsion angles in proteins  from 13C, 15N and 1H chemical shifts and sequential homology. PREDITOR's accuracy in predicting φ and ψ is close to 90%. Go to the service >>


RCI webserver predicts protein flexibility by calculating the Random Coil Index from backbone chemical shifts (Cα, CO, Cβ, N, Hα, NH) and estimating values of model-free order parameters as well as per-residue RMSF of NMR and MD ensembles from the Random Coil Index. Go to the service >>


UPLABEL is an algorithm for finding optimal labeling patterns for the backbone assignment of proteins. Go to the service >>
