Site-directed mutagenesis as a probe to study the mechanism of sheep liver 6-phosphogluconate dehydrogenase.
(2006)
All mutant enzymes in the 2'-phosphate site exhibit an increase in KNADP that ranges from 6-fold to 80-fold. A 7-fold increase in the primary kinetic 13C-isotope effect minus 1 in all mutant enzymes indicates that the ...
Understanding and design of molecular dynamics based simulation methods.
(2006)
Several new strategies for employing modified molecular dynamics (MD) protocols for finding energy minima were developed developed. First, we derived a new method of searching for the lowest energy conformation by employ ...
Iron uptake in Gram-negative and Gram-positive bacteria.
(2006)
Bacteria, including both Gram-positive and Gram-negative bacteria, utilize iron sources from the environment. Iron uptake systems in Gram-negative bacteria are well studied. Escherichia coli FepA transports certain catecholate ...
Binding and transport through ferric siderophore receptors, FepA and FhuA.
(2006)
Under iron deficient conditions, Gram-negative bacteria like E. coli secrete siderophores to chelate iron in the extracellular medium. Ligand-gated porins (LGPs) transport the ferric siderophore complexes across the outer ...
Syntheses, molecular structures, and fiber-optic infrared spectroelectrochemistry of nitrosyl metalloporphyrins containing axially bound alkoxide, thiolate, imidazole, and imidazolate ligands.
(2006)
This dissertation describes the syntheses, molecular structures, and infrared spectroelectrochemistry of nitrosyl ruthenium and osmium porphyrins containing axially bound alkoxide, thiolate, imidazole, and imidazolate ligands.
