Siglecs induce tolerance to cell surface antigens by BIM-dependent deletion of the antigen-reactive B cells
2014
Paulson, J. C. , Macauley, M. S.
Infusion of blood cells from a donor can induce humoral tolerance in a recipient and increase the probability of successful organ transplant, a clinical method defined as donor-specific transfusion (DST). Despite the clinical success of DST, the immunological mechanisms by which blood cells...

Simple Aqueous Preparation of High Activity and Stability NiFe Hydrous Oxide Catalysts for Water Oxidation
Download2016-10-27
Wang, Chao, Moghaddam, Reza B., Brett, Michael J., Bergens, Steven H.
A series of Ni1–xFex hydrous oxide nanoparticles (HO-nps, x = 0–0.5, 1) were prepared by stirring 0.1 M KOH solutions of NiCl2 and FeCl2 under air at room temperature. The resulting HO-nps can be used directly, or washed and isolated without loss of activity. The Ni1–xFex HO-nps are outstandingly...

Li, Xue, Serpe, Michael J., Gao, Yongfeng
Poly (N-isopropylacrylamide) (pNIPAm)-based hydrogels and hydrogel particles (microgels) have been extensively studied since their discovery a number of decades ago. While their utility seems to have no limit, this feature article is focused on their development and application for sensing small...

Li, Xue, Serpe, Michael J., Gao, Yongfeng
Responsive polymer-based materials (or smart materials) have found numerous uses over the years due to their ease of synthesis and various responsivities/functionalities. Of them, stimuli-responsive hydrogel particles (microgels) have generated a lot of interest, and have been used for a number...

Streptococcus pneumoniae endohexosaminidase D, structural and mechanistic insight into substrate-assisted catalysis in family 85 glycoside hydrolases
Download2009
Abbott, D. W., Boraston, Alisdair B. , Vocadlo, David J., Macauley, Matthew S.
Endo-β-d-glucosaminidases from family 85 of glycoside hydrolases (GH85 endohexosaminidases) act to cleave the glycosidic linkage between the two N-acetylglucosamine units that make up the chitobiose core of N-glycans. Endohexosaminidase D (Endo-D), produced by Streptococcus pneumoniae, is...

Okon, Mark, Schulman, Brenda A., Macauley, Matthew S., McIntosh, Lawrence P., Mackereth, Cameron D., Schärpf, Manuela, Errington, Wesley J.
Although sumoylation regulates a diverse and growing number of recognized biological processes, the molecular mechanisms by which the covalent attachment of the ubiquitin-like protein SUMO can alter the properties of a target protein remain to be established. To address this question, we have...

Structural basis for antibody recognition in the receptor-binding domains of toxins A and B from Clostridium difficile
Download2014
Ng, Kenneth K. S., Tanha, Jamshid, Kitova, Elena N., Eugenio, Luiz, Murase, Tomohiko, Klassen, John S., Hussack, Greg, Schorr, Melissa
Clostridium difficile infection is a serious and highly prevalent nosocomial disease in which the two large, Rho-glucosylating toxins TcdA and TcdB are the main virulence factors. We report for the first time crystal structures revealing how neutralizing and non-neutralizing single-domain...

Structure and stability of carbohydrate-lipid interactions: Methylmannose polysaccharide-fatty acid complexes
Download2016
Klassen, John S., Siuda, Iwona, Renaud, Justin, Tieleman, D. Peter, Kitova, Elena N., Liu, Lan, Mayer, Paul M., Richards, Michele R., Lowary, Todd L.
We report a detailed study of the structure and stability of carbohydrate–lipid interactions. Complexes of a methylmannose polysaccharide (MMP) derivative and fatty acids (FAs) served as model systems. The dependence of solution affinities and gas-phase dissociation activation energies (Ea) on FA...

Synthesis of a homologous series of galactofuranose-containing mycobacterial arabinogalactan fragments
Download2019-01-31
Mycobacteria, including the human pathogen Mycobacterium tuberculosis the causative agent of tuberculosis, produce a complex cell wall structure made of carbohydrates and lipids. The major structural element of the mycobacterial cell wall is a glycoconjugate called the mycolic...
