MECHANISTIC INVESTIGATION OF ADDITIONS TO ALKENES
(2009)
We have conducted correlation studies on ten alkene addition reactions in this project in order to explore the substituent effects on alkene reactivity in these reactions. In these studies, we have correlated the relative ...
Effect of lipid modification and AcrA-lipid interactions on the structure and oligomerization of AcrA
(2009)
A wide range of antibacterial agents including antibiotics can be expelled out of the cell by AcrAB-TolC complex. In this complex, the membrane fusion protein AcrA is located in the periplasm and essential for drug efflux. ...
DIRECT METAGENOMIC DETECTION AND ANALYSIS OF PLANT VIRUSES USING AN UNBIASED HIGH-THROUGHPUT SEQUENCING APPROACH
(2009)
It is well established that plants, along with other life forms, often are infected by viral parasites that require the host cellular machinery for replication. Since the overwhelming majority of these viruses have been ...
Mechanisms of Serine Acetyltransferase and O-Acetylserine Sulfhydrylase
(2009)
The de novo biosynthesis of L-cysteine in enteric bacteria and higher plants is a two-step pathway. The first step is catalyzed by serine acetyltransferase (SAT), which converts acetyl CoA and L-serine to O-acetyl-L-serine ...
In Vitro Study of Histatins: Studies of the Free and Copper Complexed Bioligand's Structure and Catalytic Activity.
(2009)
The ability of the histidine-rich peptides, histatin-5 (Hst-5) and -8 (Hst-8), to support the generation of reactive oxygen species (ROS) during the copper-catalyzed oxidation of ascorbate and cysteine has been evaluated. ...
Solgel Silicates: Thickness Control and Interactions with Cucurbit[7]uril/Dye Complexes
(2009)
This work reports the progress made in investigating the versatility of solgel silicate thickness control and hosting capabilities for use in sensor and optical material technologies. Thickness control of the solgel ...
MOLECULAR DYNAMICS STUDIES OF BENZENE-d6 ASSOCIATED WITH BLACK CARBON MATERIALS BY LINE SHAPE ANALYSIS OF STATIC SOLID-STATE 2H NUCLEAR MAGNETIC RESONANCE SPECTRA
(2009)
Black carbons in the atmosphere, in soils, and in sediments strongly sorb hydrophobic organic contaminants and function as agents of transport, sequestration, and catalysis. There is a need to examine the specific sorption ...

SYNTHESIS OF STRUCTURAL MODELS OF NON-HEME DIOXYGENASES. MIMICS OF THE 3-His-1-CARBOXYLATE TETRAD
(2009)
Metalloenzymes catalyze various reactions and in particular dioxygenases insert dioxygen into organic substrates. Since these enzymes usually utilize histidines as ligands for the metal cofactor, we focused our attention ...
