Ion Spectroscopy Reveals Structural Difference for Proteins Microhydrated by Retention and Condensation of Water

Protein ubiquitin in its +7 charge state microhydrated by 5 and 10 water molecules has been interrogated in the gas phase by cold ion UV/IR spectroscopy. The complexes were formed either by condensing water onto the unfolded bare proteins in a temperature- ...

The CRL5-SPSB3 ubiquitin ligase targets nuclear cGAS for degradation

Andrea Ablasser, Baptiste Claude André Guey, Jonathan Jean-Pierre Ricci, Chong Liu, Pauline Ambre Melenec, Pengbiao Xu, Lingyun Li, Ying Liu

Cyclic GMP-AMP synthase (cGAS) senses aberrant DNA during infection, cancer and inflammatory disease, and initiates potent innate immune responses through the synthesis of 2 ' 3 '-cyclic GMP-AMP (cGAMP)1-7. The indiscriminate activity of cGAS towards DNA d ...

A chemical biology approach to decipher chromatin ubiquitylation by RNF168

Pauline Franz

DNA damage signaling following DNA double-strand breaks (DSBs) involves numerous regulating proteins, which dynamically recognize ('read') and alter ('write' or 'erase') histone post-translational modifications (PTMs). Among these PTMs, the ubiquitin syste ...

Gentle nano-electrospray ion source for reliable and efficient generation of microsolvated ions

Oleg Boyarkine, Andrei Zviagin, Vladimir Kopysov

We present herein the design of a nano-electrospray ion source capable of reliable generation of large quantities of microsolvated ions. The source is based on a triple molecular skimmer scheme and can be quickly tuned to generate bare ions or their ionic ...

A minimalistic cyclic ice-binding peptide from phage display

Harm-Anton Klok, Luciano Andres Abriata, Matthew Gibson, Xudong Kong, Corey Alfred Stevens

Developing molecules that emulate the properties of naturally occurring ice-binding proteins (IBPs) is a daunting challenge. Rather than relying on the (limited) existing structure–property relationships that have been established for IBPs, here we report ...

Similarities and Differences among Protein Dynamics Studied by Variable Temperature Nuclear Magnetic Resonance Relaxation

David Lyndon Emsley, Jayasubba Reddy Yarava, Andrea Bertarello, Baptiste Busi, François Freymond

Understanding and describing the dynamics of proteins is one of the major challenges in biology. Here, we use multifield variable-temperature NMR longitudinal relaxation (R-1) measurements to determine the hierarchical activation energies of motions of fou ...

Hypervalent Iodine-Mediated Late-Stage Peptide and Protein Functionalization

Jérôme Waser, Elija Grinhagena, Emmanuelle Madeline Dominique Allouche

Hypervalent iodine compounds are powerful reagents for the development of novel transformations. As they exhibit low toxicity, high functional group tolerance, and stability in biocompatible media, they have been used for the functionalization of biomolecu ...

KAP1 is an antiparallel dimer with a functional asymmetry

Didier Trono, Matteo Dal Peraro, Beat Fierz, Davide Demurtas, Louise Catherine Bryan, Maria Josefina Marcaida Lopez, Giulia Fonti, Pierre-Yves Joseph Laurent Helleboid, Alexandra Styliani Kalantzi

KAP1 (KRAB domain-associated protein 1) plays a fundamental role in regulating gene expression in mammalian cells by recruiting different transcription factors and altering the chromatin state. In doing so, KAP1 acts both as a platform for macromolecular i ...

Generation of Native, Untagged Huntingtin Exon1 Monomer and Fibrils Using a SUMO Fusion Strategy

Hilal Lashuel, Jonathan Jean-Pierre Ricci, Anass Chiki, Andreas Reif

Huntington’s Disease (HD) is an inherited fatal neurodegenerative disease caused by a CAG expansion (36) in the first exon of the HD gene, resulting in the expression of the Huntingtin protein (Htt) or N-terminal fragments thereof with an expanded polygl ...
