Prediction and design of protein structures

Resumen
Rosetta predictions in the Fifth and Sixth Community-Wide Experiment on the Critical Assessment of Techniques for Protein Structure Prediction (CASP) are presented, focusing on the free modeling category. The application of this prediction technique for rapid protein fold elucidation from unassigned NMR spectra is illustrated. NMR spectroscopy has the advantage of rapidly providing the structurally relevant information in the form of unassigned chemical shifts (CSs), intensities of NOESY crosspeaks [nuclear Overhauser effects (NOEs)], and residual dipolar couplings (RDCs). We developed a method for generating low-resolution protein structures by using unassigned NMR data that relies on de novo protein structure prediction algorithm and Monte Carlo procedure that searches for the assignment of resonances to atoms that produces the best fit of the experimental NMR data to a candidate 3D structure. Protein small molecule docking algorithms provide a means to elucidate the interface of presently unknown protein small molecule complexes in structural detail. Here I present and evaluate a new method that docks a rigid-body small molecules into protein binding sites employing a simultaneous Monte-Carlo search for position, orientation, and protein sidechain conformation. In the last part of this presentation protein design algorithms are discussed on the example of the de novo designed protein fold of TOP7. This method was expanded on the design of protein-ligand interfaces.
