Solid-state nuclear magnetic resonance (ssNMR) is a spectroscopic technique that is used for characterization of molecular properties in the solid phase at atomic resolution. In particular, using the approach of magic-angle spinning (MAS), ssNMR has seen widespread applications for topics ranging from material sciences to catalysis, metabolomics, and structural ...

Heat shock protein 90 (Hsp90) is a dimeric molecular chaperone that undergoes large conformational changes during its functional cycle. It has been established that conformational switch points exist in the N-terminal (Hsp90-N) and C-terminal (Hsp90-C) domains of Hsp90, however information for switch points in the large middle-domain (Hsp90-M) is scarce. Here we ...

Das RGD‐erkennende Integrin αvβ6 trat in jüngster Zeit als vielbeachtete Zielstruktur für die Diagnostik und Therapie von Krebserkrankungen in Erscheinung. Infolgedessen besteht derzeit ein dringender Bedarf an niedermolekularen Liganden für diesen Rezeptor. Ein auf Metadynamik beruhender Ansatz ermöglichte die erfolgreiche Konvertierung eines helikalen ...

In the eukaryotic nucleus, DNA is packaged in the form of nucleosomes, each of which comprises about 147 base pairs of DNA wrapped around a histone protein octamer. The position and histone composition of nucleosomes is governed by ATP-dependent chromatin remodellers such as the 15-subunit INO80 complex. INO80 regulates gene expression, DNA repair and replication ...

Ultrastable cyclic peptide frameworks offer great potential for drug design due to their improved bioavailability compared to their linear analogues. Using the sunflower trypsin inhibitor-1 (SFTI-1) peptide scaffold in combination with systematic N-methylation of the grafted pharmacophore led to the identification of novel subtype selective melanocortin receptor ...

Specific targeting of the integrin subtype α5β1 possesses high potential in cancer diagnosis and therapy. Through sequential N-methylation, we successfully converted the biselective α5β1/αvβ6 peptide c(phg-isoDGR-k) into a potent peptidic RGD binding α5β1 subtype selective ligand c(phg-isoDGR-(NMe)k). Nuclear magnetic resonance spectroscopy and molecular modeling ...

The epithelial integrin αvβ6 is expressed by many malignant carcinoma cell types, including pancreatic cancer, and thus represents a promising target for radionuclide therapy. The peptide cyclo(FRGDLAFp(NMe)K) was decorated with different chelators (DOTPI, DOTAGA, and DOTA). The Lu(III) complexes of these conjugates exhibited comparable αvβ6 integrin affinities ...

Solid-state NMR has been employed for characterization of a broad range of biomacromolecules and supramolecular assemblies. However, because of limitations in sensitivity and resolution, the size of the individual monomeric units has rarely exceeded 15 kDa. As such, enzymes, which are often more complex and comprise long peptide chains, have not been easily ...
