Software for Real-space Refinement of Macromolecular Structures: Software to Improve the Fit of Biomolecular Models to Experimental Images

 

OHSU # 1742

Summary:

Value Proposition:

Researchers at Oregon Health & Science University have developed software that utilizes real-space refinement to optimize atomic models of macromolecules fit into experimental electron density maps obtained either by x-ray crystallography or 3D electron microscopy. Real-space refinement optimizes the agreement between density simulated from an atomic model and an experimental map thus improving the accuracy of models based on x-ray diffraction or even lower resolution electron microscopy. This software can either be utilized as a standalone application or can be incorporated in other programs that support the use of additional stereochemical restraints to achieve a model precision that is beyond the nominal experimental resolution.

Inventor Profile:

Dr. Michael Chapman is a Professor in the Department of Biochemistry and Molecular Biology at Oregon Health & Science University. The Chapman lab develops biophysical methods for visualizing molecular interaction and applies them in two distinct areas: vial-host interactions and the fundamentals of enzyme mechanism.
