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 ...

Mycobacterium tuberculosis Resists Stress by Regulating PE19 Expression

John McKinney, Anna De Graff Tischler

Mycobacterium tuberculosis requires the phosphate-sensing signal transduction system Pst/SenX3-RegX3 to resist host immune responses. A Delta pstA1 mutant lacking a Pst phosphate uptake system component is hypersensitive to diverse stress conditions in vit ...

Phage Selection of Bicyclic Peptides and High-Throughput Screening of Chemical Compounds for the Identification of Novel Inhibitors of the Notch Pathway

Charlotte Marie Urech-Varenne

Notch signaling is a highly conserved developmental pathway that plays important roles in the regulation of cellular processes including cell fate decisions and stem cell maintenance. A tight regulation of the Notch cascade ensures proper tissue homeostasi ...

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 ...

Dithiol amino acids can structurally shape and enhance the ligand-binding properties of polypeptides

Christian Heinis, Rudolf Hovius, Florence Pojer, Shiyu Chen, Ranganath Gopalakrishnan

The disulfide bonds that form between two cysteine residues are important in defining and rigidifying the structures of proteins and peptides. In polypeptides containing multiple cysteine residues, disulfide isomerization can lead to multiple products with ...

A New Role for Escherichia coli DsbC Protein in Protection against Oxidative Stress

Camille Véronique Bernadette Goemans

We report a new function for Escherichia coli DsbC, a protein best known for disulfide bond isomerization in the periplasm. We found that DsbC regulates the redox state of the single cysteine of the l-arabinose-binding protein AraF. This cysteine, which ca ...

Mechanistic effects of protein palmitoylation and the cellular consequences thereof

Françoise Gisou van der Goot Grunberg, Sanja Blaskovic, Mathieu Blanc

S-palmitoylation involves the attachment of a 16-carbon long fatty acid chain to the cysteine residues of proteins. The process is enzymatic and dynamic with DHHC enzymes mediating palmitoylation and acyl-protein thioesterases reverting the reaction. Prote ...

Regulation of TGF beta and related signals by precursor processing

Daniel Constam

Secreted cytokines of the TGF beta family are found in all multicellular organisms and implicated in regulating fundamental cell behaviors such as proliferation, differentiation, migration and survival. Signal transduction involves complexes of specific ty ...

Improving Bicyclic Peptide Phage Display and Development of Sortase A Inhibitors

Inmaculada Rentero Rebollo

Bicyclic peptide ligands are promising molecules for the development of new therapeutics. They combine advantages from large protein therapeutics and small molecule drugs. Large combinatorial libraries of bicyclic peptides can be generated and screened by ...
