Replacing Arginine 33 for Alanine in the Hemophore HasA from Pseudomonas aeruginosa Causes Closure of the H32 Loop in the Apo-Protein
(ACS Publications, 2016-05)Previous characterization of hemophores from Serratia marcescens (HasAs), Pseudomonas aeruginosa (HasAp) and Yersinia pestis (HasAyp) showed that hemin binds between two loops, where it is axially coordinated by H32 and ... -
Microfluidic Exosome Analysis toward Liquid Biopsy for Cancer
(Sage, 2016-08)Assessment of a tumor’s molecular makeup using biofluid samples, known as liquid biopsy, is a prominent research topic in precision medicine for cancer, due to its noninvasive property allowing repeat sampling for monitoring ... -
Spectroscopic and Computational Investigation of Low-Spin MnIII Bis(scorpionate) Complexes
(Wiley, 2016-06)Six-coordinate MnIII complexes are typically high-spin (S = 2), however, the scorpionate ligand, both in its traditional, hydridotris(pyrazolyl)borate form, Tp– and Tp*– (the latter with 3,5-dimethylpyrazole substituents) ... -
GlycoPep MassList: Software to Generate Massive Inclusion Lists for Glycopeptide Analyses
(Springer Verlag, 2017-01)Protein glycosylation drives many biological processes and serves as markers for disease; therefore, the development of tools to study glycosylation is an essential and growing area of research. Mass spectrometry can be ... -
Low-Dimensional FeS2 Nanostructures for use as Hydrogen Evolution Electrocatalysts
(University of Kansas, 2015-05-31)The water splitting hydrogen evolution reaction which is used as an alternative method of hydrogen production currently relies on platinum group metal electrocatalysts to function. Currently this method accounts for only ... -
Hybrid antimalarials; the reaction of 8-amino-quinolines with nitrodiols
(University of Kansas, 1950-05)Malaria is one of the oldest diseases known to man, and, even today, with the great advances in medical science, it affects a large percentage of the human race. It has been estimated that.the disease attacks several ... -
A new derivative method for the identification of olefins
(University of Kansas, 1947-05) -
Metal complexes with varying intramolecular hydrogen bonding networks
(Elsevier, 2013-03-01)Alfred Werner described the attributes of the primary and secondary coordination spheres in his development of coordination chemistry. To examine the effects of the secondary coordination sphere on coordination chemistry, ... -
2-Diazo-1-(4-hydroxyphenyl)ethanone: A Versatile Photochemical and Synthetic Reagent
(Royal Society of Chemistry, 2014-02)α-Diazo arylketones are well-known substrates for Wolff rearrangement to phenylacetic acids through a ketene intermediate by either thermal or photochemical activation. Likewise, α-substituted p-hydroxyphenacyl (pHP) esters ... -
The permeation of dynorphin A 1–6 across the blood brain barrier and its effect on bovine brain microvessel endothelial cell monolayer permeability
(Elsevier, 2012-12)Dynorphin A 1–17 (Dyn A 1–17) is an endogenous neuropeptide known to act at the kappa opioid receptor; it has been implicated in a number of neurological disorders, including neuropathic pain, stress, depression, and ... -
Enthalpy vs Entropy Driven Complexation of Homoallylic Alcohols by Rh(I) Complexes
(American Chemical Society, 2011-10-25)The thermodynamics of binding between several homoallylic alcohols and simple olefinic Rh(I) compounds was examined with 1H NMR spectroscopy and ITC. 1H NMR titrations revealed moderate binding of these alcohols with ... -

(Springer Verlag, 2011-09)LipidomeDB Data Calculation Environment (DCE) is a web application to quantify complex lipids by processing data acquired after direct infusion of a lipid-containing biological extract, to which a cocktail of internal ... -
Fuming Method for Micropatterning Structures on Langmuir- Blodgett Films
(American Chemical Society, 2009-05-05)Lipid monolayers of L-α-dipalmitoylphosphatidylcholine (DPPC) are used to pattern substrates using the Langmuir-Blodgett (LB) technique. Lipid monolayers are deposited onto a freshly cleaved mica surface or glass capillary ... -
Isotope Effects and Temperature Dependences in the Action of the Glucose Dehydrogenase of the Mesophilic Bacterium Bacillus megaterium
(Wiley, 2013-12-01)The glucose dehydrogenase of the mesophilic bacterium Bacillus megaterium (optimal growth around 35 °C) exhibits non-linear Eyring temperature dependences from 25 to 55 °C in its catalysis of the oxidation by hydride-transfer ... -
Partial cooperative unfolding in proteins as observed by hydrogen exchange mass spectrometry
(Taylor & Francis, 2013-01-01)Many proteins do not exist in a single rigid conformation. Protein motions, or dynamics, exist and in many cases are important for protein function. The analysis of protein dynamics relies on biophysical techniques that ... -
