O-GlcNAcase uses substrate-assisted catalysis Kinetic analysis and development of highly selective mechanism-inspired inhibitors
Download2005
Vocadlo, David J., Whitworth, Garrett E., Macauley, Matthew S., Debowski, Aleksandra W., Chin, Danielle
The post-translational modification of serine and threonine residues of nucleocytoplasmic proteins with 2-acetamido-2-deoxy-d-glucopyranose (GlcNAc) is a reversible process implicated in multiple cellular processes. The enzyme O-GlcNAcase catalyzes the cleavage of β-O-linked GlcNAc (O-GlcNAc)...

Howell, P. Lynne, Klassen, John S., Robinson, Howard, Kitova, Elena N., Dawson, Karen, Clarke, Anthony J., Little, Dustin J., Walvoort, Marthe T., Weadge, Joel T., Codee, Jeroen D. C., Baker, Perrin, Whitney, John C., Ohman, Dennis E., Ricer, Tyler, Moynihan, Patrick J.
The O-acetylation of polysaccharides is a common modification used by pathogenic organisms to protect against external forces. Pseudomonas aeruginosa secretes the anionic, O-acetylated exopolysaccharide alginate during chronic infection in the lungs of cystic fibrosis patients to form the major...

Photothermally induced optical property changes of poly(N-isopropylacrylamide) microgel-based etalons
Download2015
Islam, Molla R., Irvine, Jessica, Serpe, Michael J.
Poly(N-isopropylacrylamide) microgel-based optical devices were designed such that they can be stimulated to change their optical properties in response to light produced by a light-emitting diode (LED). The devices were fabricated by sandwiching the synthesized microgels between two Cr/Au layers...

Protein interactions with glycolipids are implicated in diverse cellular processes. However, the study of protein–glycolipid complexes remains a significant experimental challenge. Here, we describe a powerful new assay that combines electrospray ionization mass spectrometry (ESI-MS) and...

Poly (N-isopropylacrylamide) microgel-based etalons and etalon arrays for determining the molecular weight of polymers in solution
Download2013
Serpe, Michael J., Islam, Molla R.
Positively and/or negatively charged poly (N-isopropylacrylamide)-based microgels were deposited on a single substrate and isolated regions of Au overlayers were deposited on top of the microgels. Each spatially isolated Au overlayer region had a different thickness to make an etalon array. We...

Poly (N-isopropylacrylamide) (pNIPAm) is one of the most completely studied “smart” polymers due to its unique reversible thermoresponsivity. That is, when pNIPAm in water is heated > ~31°C, it transits from a random coil to a globule conformation; this transition is reversed when T < ~31°C. This...

Zhang, Qiang M., Serpe, Michael J., Han, De-Man
Poly (N-isopropylacrylamide)-co-(acrylic acid) (pNIPAm-co-AAc) microgels composed of Ag nanoparticles (Ag NPs) have been synthesized and employed for the colorimetric sensing of H2O2. Each pNIPAmco-AAc microgel, which exhibited a diameter of ∼800 nm, contained multiple Ag NPs (diameter of ∼5 nm),...
