Serpe, Michael J., Xu, Wenwen, Gao, Yongfeng
In this submission, pH responsive poly(N-isopropylacrylamide)–based microgels were used to fabricate optical devices (etalons). We demonstrate that the optical properties of the etalons could be manipulated upon the application of an appropriate electric potential between the etalon and a counter...

Klassen, John S., Lin, Hong, Kitova, Elena N., Ng, Kenneth K., Johnson, M. A., Eugenio, Luiz
Electrospray ionization mass spectrometry (ESI-MS) measurements were performed under a variety of solution conditions on a highly acidic sub-fragment (B3C) of the C-terminal carbohydrate-binding repeat region of Clostridium difficile toxin B, and two mutants (B4A and B4B) containing fewer acidic...

Elevation of global O-GlcNAc levels in 3T3-L1 adipocytes by selective inhibition of O-GlcNAcase does not induce insulin resistance

Bubb, Abigail K., Macauley, Matthew S., Davies, Gideon J., Vocadlo, David J. , Martinez-Fleites, Carlos
The O-GlcNAc post-translational modification is considered to act as a sensor of nutrient flux through the hexosamine biosynthetic pathway. A cornerstone of this hypothesis is that global elevation of protein O-GlcNAc levels, typically induced with the non-selective O-GlcNAcase inhibitor PUGNAc...

Kitova, Elena N., Klassen, John S., Michelsen, Klaus, Liu, Lan, Schnier, Paul D., Baergen, Alyson
This work explores the energetics of intermolecular H-bonds inside a hydrophobic protein cavity. Kinetic measurements were performed on the gaseous deprotonated ions (at the −7 charge state) of complexes of bovine β-lactoglobulin (Lg) and three monohydroxylated analogs of palmitic acid (PA):...

Brianne M. Zorzetti, Jeremy M. Shaver, and James J. Harynuk
The ability to predict the amount of time that a light petroleum mixture has been weathered could have many applications, such as aiding forensic investigators in determining the cause and intent of a fire. In our study, an evaporation chamber that permits control of airflow and temperature was...

Excited-state Dynamics of Alizarin-Sensitized TiO2 Nanoparticles from Resonance Raman Spectroscopy
Download2002-01-01
Shoute, Lian C. T., Loppnow, Glen R.
Resonance Raman spectra of alizarin-sensitized TiO2 nanoparticles have been obtained at excitation wavelengths throughout the 488-nm charge transfer absorption band. The resonance Raman spectrum of the alizarin-sensitized TiO2 nanoparticle is significantly different from the spectrum of free...

Exploiting bacterial glycosylation machineries for the synthesis of a Lewis antigen-containing glycoprotein
Download2011
Hug, Isabelle, Reiz, Bela, Fentabil, Messele A., Klassen, John S., Whittal, Randy M., Zheng, Blake, Feldman, Mario F.
Glycoproteins constitute a class of compounds of increasing importance for pharmaceutical applications. The manipulation of bacterial protein glycosylation systems from Gram-negative bacteria for the synthesis of recombinant glycoproteins is a promising alternative to the current production...

This paper reports on the first experimental study of the energies of noncovalent fluorine bonding in a protein-ligand complex in the absence of solvent. Arrhenius parameters were measured for the dissociation of gaseous deprotonated ions of complexes of bovine β-lactoglobulin (Lg), a model...
