Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Proteomic Analysis of Covalent Modifications of Tubulins by Isothiocyanates [PDF]

The Journal of Nutrition, 2012
Although isothiocyanates (ITC), which are found in cruciferous vegetables, have been shown to inhibit carcinogenesis in animal models and induce apoptosis and cell cycle arrest in tumor cells, the biochemical mechanisms of cell growth inhibition by these compounds are not fully understood.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Rapid pre-gel visualization of proteins with mass spectrometry compatibility [PDF]

, 2010
Despite all of the prophecies of doom, gel electrophoresis is still prevalent in modern proteomic workflows. However, the currently used protein staining methods represent a serious bottleneck for a quick subsequent protein analysis using mass ...

Covalent Modification Cycles through the Spatial Prism [PDF]

Biophysical Journal, 2013
Covalent modification cycles are basic units and building blocks of posttranslational modification and cellular signal transduction. We systematically explore different spatial aspects of signal transduction in covalent modification cycles by starting with a basic temporal cycle as a reference and focusing on steady-state signal transduction.

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Covalent attachment of phenyl and carboxyphenyl layers derived from diazonium salts onto activated charcoal for the adsorption of pesticides

Macedonian Journal of Chemistry and Chemical Engineering, 2018
The past and recent uncontrolled use of organochlorine pesticides imposes serious problems due to their adverse undesired effects in ecosystems. Finding new ways to dispose of these molecules is therefore mandatory. The covalent modification of activated
