Abstract

A new approach to the calculation of the spatial protein structure based on the joint utilization of the theoretical conformational analysis method and nuclear Overhauser enhancement (NOE) spectroscopy data is proposed and verified. The quality in determining various molecule structural parameters is estimated in terms of the expected NOE spectral parameters derived from the X-ray analysis data of the avian pancreatic polypeptide. The proposed approach is shown to correctly determine such structural parameters of protein molecules as local amino acid residue conformations, reciprocal spatial orientation of the C alpha atoms neighbouring along amino acid sequence and reapproached segments of the polypeptide chain. Spatially remote molecule fragments are mainly responsible for the error in determining structural parameters.
