alpha-Synuclein O-GlcNAcylation alters aggregation and toxicity, revealing certain residues as potential inhibitors of Parkinson's disease

Hilal Lashuel, Anne-Laure Mahul Mellier

A compelling link is emerging between the posttranslational modification O-GlcNAc and protein aggregation. A prime example is alpha-synuclein, which forms toxic aggregates that are associated with neurodegeneration in Parkinson's and related diseases. alph ...

Folding and Endocytosis of Anthrax Toxin Receptors

Bacillus anthracis is the causative agent of the infectious disease anthrax. The disease is caused after taking up the spores by either inhalation, ingestion or through skin lesion. They then germinate inside the body and start secreting the tripartite ant ...

A comparison of orbitally-shaken and stirred-tank bioreactors: pH modulation and bioreactor type affect CHO cell growth and protein glycosylation

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Marc Moniatte, Dominique Terry Monteil Jr, Valentin Juvet

Orbitally shaken bioreactors (OSRs) support the suspension cultivation of animal cells at volumetric scales up to 200 L and are a potential alternative to stirred-tank bioreactors (STRs) due to their rapid and homogeneous mixing and high oxygen transfer ra ...

Branched Lateral Tail Fiber Organization in T5-Like Bacteriophages DT57C and DT571/2 is Revealed by Genetic and Functional Analysis

Ricardo Cesar Guerrero Ferreira, Nikolai Prokhorov

The T5-like siphoviruses DT57C and DT571/2, isolated from horse feces, are very closely related to each other, and most of their structural proteins are also nearly identical to T5 phage. Their LTFs (L-shaped tail fibers), however, are composed of two prot ...

Molecular Mechanism of Flocculation Self-Recognition in Yeast and Its Role in Mating and Survival

Sandor Kasas, Livan Bladimir Alonso Sarduy, Jens Nielsen

We studied the flocculation mechanism at the molecular level by determining the atomic structures of N-Flo1p and N-Lg-Flo1p in complex with their ligands. We show that they have similar ligand binding mechanisms but distinct carbohydrate specificities and ...

N-linked sugar-regulated protein folding and quality control in the ER

Maurizio Molinari

Asparagine-linked glycans (N-glycans) are displayed on the majority of proteins synthesized in the endoplasmic reticulum (ER). Removal of the outermost glucose residue recruits the lectin chaperone malectin possibly involved in a first triage of defective ...

Production of active glycosylation-deficient gamma-secretase complex for crystallization studies

Florian Maria Wurm, David Hacker, Patrick Fraering, Virginie Sandra Braman, Mitko Dimitrov, Hermeto Gerber, Andres Ricardo Lopez Robles

Alzheimer's disease (AD)-associated gamma-secretase is a ubiquitously expressed multi-subunit protease complex embedded in the lipid bilayer of cellular compartments including endosomes and the plasma membrane. Although gamma-secretase is of crucial intere ...

Hepatic glucose sensing and integrative pathways in the liver

Kristina Schoonjans, Maaike Hélène Oosterveer

The hepatic glucose-sensing system is a functional network of enzymes and transcription factors that is critical for the maintenance of energy homeostasis and systemic glycemia. Here we review the recent literature on its components and metabolic actions. ...

Adducts of Nitrous Oxide and N-Heterocyclic Carbenes: Syntheses, Structures, and Reactivity

Rosario Scopelliti, Kay Severin, Euro Solari, Basile Vuichoud, Alexander Tskhovrebov

N-Heterocyclic carbenes (NHCs) react at ambient conditions with nitrous oxide to give covalent adducts. In the crystal, all compounds show a bent N2O group connected via the N-atom to the former carbene carbon atom. Most adducts are stable at room temperat ...
