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 ...
Bipolar Electrochemistry: Chemical Analysis Based on Electrochemiluminescence and Surface Enhanced Raman Spectroscopy
(2015-07-24)
Bipolar electrochemistry has a variety of applications ranging from chemical analysis, material modification and synthesis, to generate motions, etc, and it is also a very simple, cheap, useful technology. The main goal ...
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 ...
Activation and Inhibitor Studies on Methyl-Coenzyme M Reductase and Purification of a New Hydroxylamine Oxidoreductase from Methylomicrobium Album ATCC 33003
(2009-02-23)
Methyl-coenzyme M reductase (MCR) catalyzes the formation of methane from methyl-coenzyme M (CH3-S-CoM) and coenzyme B (HS-CoB) in methanogenic archaea. In order to manage the overproduction of methane in the environment, ...
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 ...
Design and Properties of Novel Uranium-Containing Layered and Framework Materials
(2008-09-09)
Ten uranyl-containing frameworks and one layered material have been
synthesized under hydrothermal conditions. These compounds belong to eight structure
types, not previously described. They are constructed from uranyl ...
