Summary
Quantum refinement of DNA X-ray structures. DNA carries the genetic map of life and refinement of its x-ray structures is a key tool to understand its functions. Standard refinement, however, relies strongly on empirical geometry constraints, and it is known that these can induce unphysical features. Quantum mechanical (QM) methods have now evolved to a level that offers an intriguing way out of this dilemma. In this project, state-of-the-art QM methods will be applied to DNA x-ray structures, a ....Quantum refinement of DNA X-ray structures. DNA carries the genetic map of life and refinement of its x-ray structures is a key tool to understand its functions. Standard refinement, however, relies strongly on empirical geometry constraints, and it is known that these can induce unphysical features. Quantum mechanical (QM) methods have now evolved to a level that offers an intriguing way out of this dilemma. In this project, state-of-the-art QM methods will be applied to DNA x-ray structures, and a unique quantum refinement scheme will be developed. Such a scheme will provide crystallographers with a new tool to determine DNA structures with greater accuracy and it will offer benefits to many areas of the life sciences that depend on such accurate structures.Read moreRead less

Joint Theoretical and Experimental Electron Momentum Spectroscopic Studies for DNA Bases. The study of DNA structure is an area of intense research activity and continues to reveal new levels of complexity and diversity. Recent experiments (Science, 2002) provided direct evidences of the adenine non-planarity, indicating non-rigidity of DNA bases. Electron momentum spectroscopy (EMS) has been identified to be an appropriate technique in the study of chemical binding mechanism and orbitals at mol ....Joint Theoretical and Experimental Electron Momentum Spectroscopic Studies for DNA Bases. The study of DNA structure is an area of intense research activity and continues to reveal new levels of complexity and diversity. Recent experiments (Science, 2002) provided direct evidences of the adenine non-planarity, indicating non-rigidity of DNA bases. Electron momentum spectroscopy (EMS) has been identified to be an appropriate technique in the study of chemical binding mechanism and orbitals at molecular level. The aims of the project is to study orbitals and interactions of DNA and RNA bases such as adenine, thymine (uracil), guanine and cytosine using momentum space quantum mechanics and EMS experimental techniques. The outcome of the project will improve our understanding of the DNA double helical strand structure.Read moreRead less
