MicroScale Thermophoresis as a Tool to Study Protein-peptide Interactions in the Context of Large Eukaryotic Protein Complexes
[Abstract]  Protein-peptide interactions are part of many physiological processes, for example, epigenetics where peptide regions of histone complexes are crucial for regulation of chromatin structure. Short peptides are often also used as alternatives to small molecule drugs to target protein complexes. Studying the interactions between proteins and peptides is thus an important task in systems biology, cell biology, biochemistry, and drug design. However, this task is often hampered by the drawbacks of ...

In vitro AMPylation Assays Using Purified, Recombinant Proteins
[Abstract]  Post-translational protein modifications (PTMs) orchestrate the activity of individual proteins and ensure their proper function. While modifications such as phosphorylation or glycosylation are well understood, more unusual modifications, including nitrosylation or AMPylation remain comparatively poorly characterized. Research on protein AMPylation–which refers to the covalent addition of an AMP moiety to the side chains of serine, threonine or tyrosine–has undergone a renaissance (Yarbrough et ...

Immunoprecipitation of Cell Surface Proteins from Gram-negative Bacteria
[Abstract]  The meningococcus (Neisseria meningitidis) remains an important threat to human health worldwide. This Gram-negative bacterium causes elevated disabilities and mortality in infected individuals. Despite several available vaccines, currently there is no universal vaccine against all circulating meningococcal strains (Vogel et al., 2013). Herein, we describe a new protocol that is capable of identifying only cell surface exposed proteins that play a role in immunity, providing ...
