Book Synopsis On the Determination of Three-dimensional Protein Structures by Nuclear Magnetic Resonance Methods by : Per J. Kraulis
Download or read book On the Determination of Three-dimensional Protein Structures by Nuclear Magnetic Resonance Methods written by Per J. Kraulis and published by . This book was released on 1989 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last 10 years, nuclear magnetic resonance (NMR) methods have been developed to determine the three-dimensional structures of small proteins. This thesis reviews these methods and discusses their limitations. The assignment of the NMR spectrum of a protein is a necessary, bbut not sufficient, requirement for the determinetion of its structure by NMR methods.For this purpose, an interactive graphics program ANSIG has been developed. Spectrum contours can be viewed, and cross peaks extracted, connested and assigned. Assignment lists and distance restraints lists derived from NOESY cross peak intensities can be produced. A novel algorithm for the calculation of three-dimensional protein structures from inter-proton distance restraints derived ,from NMR data has been implemented in the program NOEDIA. A data base of crystallographically determined protein structured is searched for fragments that fit the data and the protein structure is built from them. Cecropin A, an antibacterial peptide from the giant silk moth HYALOPHORA CECROPIA, was investigated in a solution containing 15% hexafluoroisopropyl alchohol. The three-dimensional structure of the 37-residue peptide was computed from the NMR data ba the simulated dynamical annealing method. It consists of two amphiphatic a-helical regions 5-21 and 24-37, whose relative orientation could not be defined. The cellulases of the filamentous fungus TRICHODERMA REESEI contain a strongly conserved small terminal domain, which is the N-terminal in two of them and C-terminal in the other two. The structure of a synthetic 36-residue peptide corresponding to the C-terminal domain of cellobiohydrolase I was determined grom NMR data using a hybrid distance geometry-dynamic simulated annealing method. The molecule is wedge-shaped and consists of an irregular triplestranded anti-parallel B-sheet. The structure is very well defined due to extensive stereospecific assignments and permits analysis of a number of side chain interactions. The first example of a 3D NMR spectrum of a protein is presented. The combination of two 2D experiments into a 3D experiment facilitates cross peak assignment and potentially increases the size of proteins amenable to structure determination ba NMR.

Available in PDF, EPUB and Kindle. Book excerpt: The three-dimensional structure of a protein molecule is the key to understanding its biological and physiological properties. A major problem in bioinformatics is to efficiently determine the three-dimensional structures of query proteins. Protein NMR structure de- termination is one of the main experimental methods and is comprised of: (i) protein sample production and isotope labelling, (ii) collecting NMR spectra, and (iii) analysis of the spectra to produce the protein structure. In protein NMR, the three-dimensional struc- ture is determined by exploiting a set of distance restraints between spatially proximate atoms. Currently, no practical automated protein NMR method exists that is without human intervention. We first propose a complete automated protein NMR pipeline, which can efficiently be used to determine the structures of moderate sized proteins. Second, we propose a novel and efficient semidefinite programming-based (SDP) protein structure determination method. The proposed automated protein NMR pipeline consists of three modules: (i) an automated peak picking method, called PICKY, (ii) a backbone chemical shift assign- ment method, called IPASS, and (iii) a protein structure determination method, called FALCON-NMR. When tested on four real protein data sets, this pipeline can produce structures with reasonable accuracies, starting from NMR spectra. This general method can be applied to other macromolecule structure determination methods. For example, a promising application is RNA NMR-assisted secondary structure determination. In the second part of this thesis, due to the shortcomings of FALCON-NMR, we propose a novel SDP-based protein structure determination method from NMR data, called SPROS. Most of the existing prominent protein NMR structure determination methods are based on molecular dynamics coupled with a simulated annealing schedule. In these methods, an objective function representing the error between observed and given distance restraints is minimized; these objective functions are highly non-convex and difficult to optimize. Euclidean distance geometry methods based on SDP provide a natural formulation for realizing a three-dimensional structure from a set of given distance constraints. However, the complexity of the SDP solvers increases cubically with the input matrix size, i.e., the number of atoms in the protein, and the number of constraints. In fact, the complexity of SDP solvers is a major obstacle in their applicability to the protein NMR problem. To overcome these limitations, the SPROS method models the protein molecule as a set of intersecting two- and three-dimensional cliques. We adapt and extend a technique called semidefinite facial reduction for the SDP matrix size reduction, which makes the SDP problem size approximately one quarter of the original problem. The reduced problem is solved nearly one hundred times faster and is more robust against numerical problems. Reasonably accurate results were obtained when SPROS was applied to a set of 20 real protein data sets.

Book Synopsis Computer Assisted Modeling by : National Research Council
Download or read book Computer Assisted Modeling written by National Research Council and published by National Academies Press. This book was released on 1987-02-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: In much of biology, the search for understanding the relation between structure and function is now taking place at the macromolecular level. Proteins, nucleic acids, and polysaccharides are macromolecule--polymers formed from families of simpler subunits. Because of their size and complexity, the polymers are capable of both inter- and intramolecular interactions. These interactions confer upon the polymers distinctive three-dimensional shapes. These tertiary configurations, in turn, determine the function of the macromolecule. Computers have become so inextricably involved in empirical studies of three-dimensional macromolecular structure that mathematical modeling, or theory, and experimental approaches are interrelated aspects of a single enterprise.
