Project description
The aim of this project is to develop novel computational tools that extend the scope of NMR spectroscopy and make possible functional and structural studies of larger proteins and biomolecular complexes. In particular, the aim is to develop a software package that will facilitate programmes in functional and structural genomics, i.e.:
(1) The identification of
interaction sites with other proteins, ligands and drugs; studies of
the conformations of excited states; and studies of molecular
dynamics.
(2) Structure determination
of larger proteins and biomolecular complexes that are not amenable
to crystallisation.
This project involves:
(1) The development of novel
computational tools that allow rapid assignment of NMR spectra for
studies of biomolecular interactions and dynamics by making optimal
use of existing (in particular structural) information, i.e. the NMR
equivalent of molecular replacement in X-ray crystallography.
(2) Extending the scope of
NMR spectroscopy by developing novel tools that allow the calculation
of structures without the need for prior spectral assignment.
(3) The development of
improved tools for the identification and quantification of signals
from NMR data.
These key scientific objectives are facilitated by the development and implementation of a series of computational algorithms involving Bayesian analysis, maximum entropy reconstruction, multi-dimensional decomposition principle component analysis, and statistical- and expert system based analysis tools. These algorithms are being implemented within a common software framework developed by the CCPN project, so that they can be flexibly employed in the development of the different tools. We are developing novel tools for the validation of structures and experimental results and mine databases for NMR and structural information crucial to the aims of the project.
