The metalloprotease ADAMTS4 generates N-truncated A4-x species and marks oligodendrocytes as a source of amyloidogenic peptides in Alzheimer's disease

Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Sandra Lehmann

Brain accumulation and aggregation of amyloid- (A) peptides is a critical step in the pathogenesis of Alzheimer's disease (AD). Full-length A peptides (mainly A1-40 and A1-42) are produced through sequential proteolytic cleavage of the amyloid precursor pr ...

More Than Black or White: Melanization and Toll Share Regulatory Serine Proteases in Drosophila

Bruno Lemaitre, Jan Paul Dudzic, Mark Austin Hanson, Igor Iatsenko

The melanization response is an important defense mechanism in arthropods. This reaction is mediated by phenoloxidases (POs), which are activated by complex extracellular serine protease (SP) cascades. Here, we investigate the role of SPs in the melanizati ...

Anthrax toxin requires ZDHHC5-mediated palmitoylation of its surface-processing host enzymes

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva

The protein acyl transferase ZDHHC5 was recently proposed to regulate trafficking in the endocytic pathway. Therefore, we explored the function of this enzyme in controlling the action of bacterial toxins. We found that ZDHHC5 activity is required for two ...

Discovery of novel competitive dihydropteridine reductase inhibitors via high throughput screening and their effect on metabolic pterin balance of fibroblast.

Yann Mathieu Pierson

The development of tool compounds for the study of the tetrahydrobiopterin (BH4) metabolic network perturbation is of interest especially in the case of oxidative and nitrosative stress genesis. A semisynthetic FRET sensor was engineered in order to study ...

Novel compartment-specific biosensors reveal a complementary subcellular distribution of bioactive Furin and PC7

Pierpaolo Ginefra

Proprotein Convertases (PCs) constitute a family of serine proteases that activate various hormones, growth factors and cell adhesion molecules by mediating endoproteolytic cleavage of their secreted inactive precursors during their transit in the secret ...

Structure-Based Drug Design and Characterization of Sulfonyl-Piperazine Benzothiazinone Inhibitors of DprE1 from Mycobacterium tuberculosis

Stewart Cole, Anthony Vocat, Jérémie Piton, Shi-Yan Caroline Foo, Andréanne Lupien

Macozinone (MCZ) is a tuberculosis (TB) drug candidate that specifically targets the essential flavoenzyme DprE1, thereby blocking synthesis of the cell wall precursor decaprenyl phosphoarabinose (DPA) and provoking lysis of Mycobacterium tuberculosis. As ...

Fluorescent Benzothiazinone Analogues Efficiently and Selectively Label Dpre1 in Mycobacteria and Actinobacteria

Paul Joseph Dyson, Stewart Cole, John McKinney, Neeraj Dhar, Thierry Laroche, Jérémie Piton, Joao Pedro De Almeida Neres, Raphael Christopher Sommer, Raju Mukherjee

Benzothiazinones (BTZ) are highly potent bactericidal inhibitors of mycobacteria and the lead compound, BTZ043, and the optimized drug candidate, PBTZ169, have potential for the treatment of tuberculosis. Here, we exploited the tractability of the BTZ scaf ...

Palmitoylation mediates membrane association of hepatitis E virus ORF3 protein and is required for infectious particle secretion

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Johann Mauron, Joël Oppliger, Maxime Matter, Noémie Oechslin

Hepatitis E virus (HEV) is a positive-strand RNA virus encoding 3 open reading frames (ORF). HEV ORF3 protein is a small, hitherto poorly characterized protein involved in viral particle secretion and possibly other functions. Here, we show that HEV ORF3 p ...

Structure of a pathogen effector reveals the enzymatic mechanism of a novel acetyltransferase family

Shuguang Yuan

Effectors secreted by the type Ill secretion system are essential for bacterial pathogenesis. Members of the Yersinia outer-protein J (YopJ) family of effectors found in diverse plant and animal pathogens depend on a protease-like catalytic triad to acetyl ...

Middle-down approaches for mass spectrometry-based protein identification and characterization

Kristina Srzentic

Mass spectrometry (MS) has emerged over the last two decades as the analytical technique of choice in systems-level protein studies, known as proteomics. Two are the MS-based approaches generally applied to proteomics: bottom-up (BU), which relies on the p ...
