Applications of Polyoxometalates as Electron Mediators
(2009-10-15)
The large variety of size, structure and elemental composition of polyoxometalates leads to a wide range of different properties. The primary goal of this dissertation is to study the structure-property relationship of ...
Towards the Understanding of Complex Biochemical Systems: the Significance of Global Protein Structure and Thorough Parametric Analysis
(2009-07-06)
Enzymes are a highly diverse set of macromolecules, and, given their size and biocatalytic significance, each is an extremely complex system to study. As such, many assumptions must be made to simplify these systems to a ...
Synthetic Explorations to Sinefungin Analogs
(2009-02-23)
Sinefungin, a natural complex nucleoside, has been isolated from the cultures of Streptomyces griseolous, and from that of Streptomyces incarnatus. It is a structural analog of S-adenosylmethionine (AdoMet) and since its ...
Studies on the Structures and Properties of Bimetallic Uranium Transition Metal and Hybrid Organic-Inorganic Compounds
(2009-06-15)
Hydrothermal synthetic methods have been utilized to synthesize many compounds containing both uranium and transition metals, as well as hybrid organic-inorganic materials. These compounds are found to adopt zero-, one-, ...
Preparation and Application of Regenerable N-Halamine Biocidal Materials
(2009-05-06)
Copolymers of an N-halamine siloxane and a quaternary ammonium salt siloxane were prepared using 5,5-dimethylhydantoin and trimethylamine as functional groups. The solubility of this siloxane copolymer in water was ...
Role of Distant, Intrasubunit Residues in Catalase-Peroxidase Catalysis: Tracing the Role of Gene Duplication and Fusion in Enzyme Structure and Function
(2009-05-08)
In spite of being positioned 30 Å away from the active site, the C-terminal domain is essential for catalase-peroxidase (KatG) function. Addition of equimolar amounts of separately expressed and isolated C-terminal domain ...
Spectroscopic and kinetic investigation of two unusual structural features found in eukaryotic cysteine dioxygenase
(2009-12-17)
Cysteine dioxygenase (CDO) is a mononuclear ferrous enzyme located at a branch-point in cysteine metabolism and catalyzes the oxidation of L-cysteine using both atoms of dioxygen. Although several studies have attempted ...
Synthesis, Spectroscopic Investigation and Immobilization Of Copper(II) Complexes as Oxidation Catalysts
(2009-08-04)
Schiff-base complexes that function as catalysts in aqueous media have been developed. The design of environmentally benign metal catalysts with multidentate ligands is a field of intense current interest. Transition metal ...
Toward a Breathable Fabric for Protection Against Airborne Toxic Chemicals, and an Olefin-Forming Cascade Reaction En Route to 2,2’-Bi(glycerol)
(2009-07-31)
Part I. Several compounds that were envisioned to interact strongly with airborne chemical warfare agents, principally organophosphorus nerve agents, were synthesized. This was part of a multi-site, multi-investigator ...
