Metals and the conformation of fibrin
… necessitates the existence of a preferred conformation for this region, the nature of which has yet to be clearly established. A novel zinc metalloproteinase isolated from puff adder venom (PAV protease) capable of specifically cleaving the di-γ-chain of transglutaminase (Factor XIIIa) …

A Study of Conformation in Disubstituted Cyclohexanes
It is well known that the intermolecular hydrogen bonding is concentration and temperature dependent. It is also well known that : 1H chemical shift of a hydroxyl proton is dependent on concentration and temperature. 1H NMR has been used to study hydrogen bonding in solution.<br/><br/>It was found …

Conformation and Stereodynamic of Hindered Aromatic System
The preparation of conformationally hindered molecules and their study by DNMR and computational methods are my thesis’s core. In the first chapter, the conformations and the stereodynamics of symmetrically ortho-disubstituted aryl carbinols and aryl ethers are described. In the second chapter, the …

Force-dependent changes in alpha-catenin conformation
… This regulation is accomplished through distinct conformational changes in the α-catenin central modulatory (M) domain and the C-terminal actin-binding domain (ABD), respectively. Force-induced unfurling of the M domain exposes a cryptic vinculin-binding site, resulting in increased vinculin …

Diamond Energy - A systematic conformation searching method
… requires a good knowledge of all low-energy conformations. A python program, Diamond Energy, was developed based on an assumption that the structures of local minima are similar to a diamond lattice. These conformers could be found by calculations with integer arithmetic and evaluated with …

Conformation and dynamics of the mammalian chromosome
… goal. We characterize the ensemble chromosome conformation in mouse embryonic stem cells, by measuring interaction, or contact, probabilities between distal genomic loci. We map and describe chromosome loops, consisting of two interacting CTCF sites co-bound by cohesin, that maintain the …

Inverse Monte Carlo simulation of biomolecular conformation and coarse-grained molecular modeling of chondroitin sulfate conformation, titration, and osmotic pressure
… can be adequately characterized by a single conformation in solution, numerous other important molecules (e.g., nucleic acids, carbohydrates, and polypeptides) exhibit conformational isomerism and disorder. For these molecules, the term "structure" does not correspond to a single conformation …

DNA Constraints for Rational Control of Macromolecular Conformation
… used as structural constraints to control RNA conformation. Based on the X-ray crystal structure of the 160-nucleotide P4--P6 RNA domain of the Tetrahymena group I intron, pairs of sites for attachment of a DNA constraint were chosen rationally. When the DNA constraint is either incompatible or …

Determining molecular conformation from distance or density data
The determination of molecular structures is of growing importance in modern chemistry and biology. This thesis presents two practical, systematic algorithms for two structure determination problems. Both algorithms are branch-and-bound techniques adapted to their respective domains. The first …

Crystallisation and chain conformation of long chain n-alkanes.
… the only one able to both identify and quantify conformational disorder present in paraffinic systems. To achieve this, methyl deformations have been widely used as "internal standards" for the normalisation of peak areas. However, in the case of n-alkanes with short chain length, such as …

Polymer Dispersity Affects Conformation of Brushes Grafted on Nanoparticles
… morphology of polymer brushes with varying chain conformation. Polymer brush properties, such as grafting density \sigma and degree of polymerization N, can drastically affect conformation of neutral and pH-responsive PGNPs and further influence their efficacy in applications. Surprisingly, how …

Biochemical and mechanical cues tune fibronectin conformation and function
The composition and conformational state of biological molecules have a profound influence on cell behavior and large-scale processes including development and disease progression. Fibronectin fibers are a prevalent component of the extracellular matrix that are believed to adopt a wide array …

Molecular Dynamics Studies of Interfacial Effects on Protein Conformation
… systems in which interfacial effects on protein conformation are of interest. In the first chapter, a detailed description of MD simulations is presented. The physical basis for the methodology is discussed, followed by a description of the algorithms implemented to carry out the simulations. The …

Novel Organophosphorus Oligomers. Synthesis and conformation of α-hydroxy phenylphosphinates
Chapter one reviews the recent progress in the synthesis of phosphonopeptides, pseudopeptides containing a phosphinic, phosphonic or phosphonamide linkage in place of an amide (peptide) linkage. It describes some of the general methods for the synthesis of these pseudopeptides; for example through …
