Structural, protonation, and complexation studies of ionophores A23187, 4-ClA23187, and 23,24-Br(2)A23187.
(2006)
A23187 is a carboxylic acid polyether ionophore best known for transporting calcium through membranes. However, it has been shown that it transports Zn 2+, Cd2+, and Mn2+ more selectively than Ca2+. Derivatives of A23187 ...
The role of membrane fusion proteins in transport of diverse substrates in bacteria.
(2007)
Multidrug resistance (MDR) efflux pumps are increasingly recognized as major contributors to resistance in clinically resistant isolates. MDR is associated with increased morbidity and mortality in hospitals and is a serious ...
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 ...
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 ...
Characterization of the second-half reaction of O-acetylserine sulfhydrylase-A and the reaction of O-acetylserine sulfhydrylase-B from Salmonella typhimurium.
(2004)
The O-acetylserine sulfhydrylase-B (OASS-B) was recently overexpressed and purified to electrophoretic homogeneity (>98% pure). Both the quantity and purity of the enzyme permit more kinetic and structurally based studies ...
Synthesis of nitrogen heterocycles via transition metal catalyzed reductive cyclizations of nitroaromatics.
(2003)
This research focuses on applying a catalyst system discovered in this laboratory, for the intermolecular allylic amination of alkenes with nitrobenzenes, to the synthesis of nitrogen heterocycles via an intramolecular ...
Synthesis of symmetrical and optically active alpha-amino acids via homologation of nickel(II) complexed glycine Schiff bases.
(2007)
In order to overcome some of the limitations associated with the previously described Ni(II) complexed NGE a new generation of modular Ni(II) complexed NGE were introduced. The flexibility of this modular design has allowed ...
Functional characterization of the phosphorelay protein MPR1 from Schizosaccharomyces pombe.
(2007)
The yeast two-hybrid assay indicates that MPR1 interacts with the response regulator domains of MAK3 (one of the three histidine kinases) and MCS4, but not with MAK1, MAK2 and PRR1. PRR1-RR weakly interacts with MAK1-HK, ...
