HOMOLOGY MODELING OF BOVINE RHODOPSIN: INVESTIGATION OF THE EFFECT OF LIPID COMPOSITION AND EQUILIBRATION ON PREDICTED STRUCTURE

BURKHARDT, JONATHAN

Abstract Details

2005, MS, University of Cincinnati, Engineering : Chemical Engineering.
Structure prediction techniques are geared at bridging the gap between protein sequencers, and the more complicated crystallographic techniques for creating three-dimensional protein structures. This work used homology modeling techniques to estimate a structure for bovine rhodopsin, the first G-protein-coupled receptor (GPCR) to have a known 3D structure, using bacteriorhodopsin as a template. Molecular dynamic simulations were performed with DMPC and POPC membranes to investigate the effect of bilayer composition. Homology modeling proved to be too limited for predicting the structure of bovine rhodopsin. The initial model differed from the crystalline structure by a RMSD value of 9.46 Ang for helical heavy atoms, which compares to 4.04 Ang from Memb-Struk, and 8.647 for just alpha carbons within the helices, which compares to 3.87 Ang from PREDICT. Results from simulations with a bilayer suggest that systems that contain DMPC show a minimal improvement relative to their POPC counterparts.
