Can Mutational Analysis Be Used To Assist Structure Determination of Peptides?

Thomas Rizzo, Valeriu Scutelnic, Chiara Masellis, Liudmila Voronina

Mutational analysis is widely used to study the relationship between sequence and structure of proteins and peptides. It is often assumed that substituting a proline with another amino acid "locks" the peptide bond in the trans conformation, allowing only ...

Selective synthesis of dimethyl ether on eco-friendly K10 montmorillonite clay

Jeremy Luterbacher, Oliver Kröcher, Florent Emmanuel Héroguel, Alimohammad Bahmanpour, Christophe Jean Baranowski

The methanol dehydration reaction was studied over environmentally benign, easily accessible and inexpensive K10 montmorillonite clay used as the catalyst at a temperature range between 200–700 °C. Nearly 100% selectivity towards dimethyl ether (DME) at 80 ...

Peptide Bond Ultraviolet Absorption Enables Vibrational Cold-Ion Spectroscopy of Nonaromatic Peptides

Vladimir Kopysov, Aleksandr Pereverzev

Peptide-bond VUV absorption is inherent to all proteins and peptides. Although widely exploited in top-down proteomics for photodissociation, this absorption has never been spectroscopically characterized in the gas phase. We have measured VUV/UV photofrag ...

A bi-terminal protein ligation strategy to probe chromatin structure during DNA damage

Beat Fierz, Sinan Kilic, Iuliia Boichenko, Carolin Christine Lechner

The cellular response to DNA damage results in a signaling cascade that primes chromatin for repair. Combinatorial post-translational modifications (PTMs) play a key role in this process by altering the physical properties of chromatin and recruiting downs ...

Practical and Scalable Synthesis of 7-Azetidin-1-yl-4-(hydroxymethyl)coumarin: An Improved Photoremovable Group

Pablo Rivera Fuentes

A robust and scalable route to prep. the 7-azetidinylated alc., a useful precursor for the photoprotection of a variety of leaving groups, and its use in the prepn. of model phosphate, sulfonate, and carbamate derivs. is presented. ...

Indole Alkaloids, Macrocycles and Heterocycles

Cyril Piemontesi

An enantioselective total synthesis of (-)-terengganensine A, a heptacyclic monoterpene indole alkaloid, was performed. A short sequence allowed to obtain the enantio-enriched target in good overall yield. The synthesis featured a key asymmetric transfer h ...

Single live cell monitoring of protein turnover reveals intercellular variability and cell cycle dependence of degradation rates

Andrea Brigitta Alber

Cells need to be able to precisely control their proteome composition in order to maintain homeostasis. This is of particular relevance in fast dividing cells, such as embryonic stem cells, since their global protein levels need to be doubled at each divis ...

In situ Studies of Peptide and Protein Assemblies at the Solid-Liquid Interface

Bart Willem Stel

At the interface between science and engineering, there is the field of biomimicry: Innovations inspired by the observation of natural, evolutionary optimized biological structures and processes. To understand the challenges of biomimicry, the concept of â ...

Single step synthesis of Schottky-like hybrid graphene - titania interfaces for efficient photocatalysis

Aleksandra Radenovic

The development of 2D nanomaterial coatings across metal surfaces is a challenge due to the mismatch between the metal microstructure and the nanoscale materials. The naturally occurring thin oxidative layer present across all metal surfaces, may lead to l ...

Amide synthesis via nickel-catalysed reductive aminocarbonylation of aryl halides with nitroarenes

Xile Hu, Chi Wai Cheung, Marten Leendert Ploeger

Aminocarbonylation of aryl halides is one of the most useful methods in amide synthesis, but nitroarenes have not been used as a nitrogen source in this method even though they are more economical and accessible than anilines. Reported here is the developm ...
