Deciphering interaction fingerprints from protein molecular surfaces using geometric deep learning

Bruno Emanuel Ferreira De Sousa Correia, Michael Bronstein, Pablo Gainza Cirauqui, Freyr Sverrisson

Predicting interactions between proteins and other biomolecules solely based on structure remains a challenge in biology. A high-level representation of protein structure, the molecular surface, displays patterns of chemical and geometric features that fin ...

Large‐Range HS‐AFM Imaging of DNA Self‐Assembly through In Situ Data‐Driven Control

Alireza Karimi, Georg Fantner, Maartje Martina Cornelia Bastings, Adrian Pascal Nievergelt, Christoph Manuel Kammer, Eva Eugene Kurisinkal, Charlène Cécile Geneviève Brillard

Understanding hierarchical self-assembly of biological structures requires real time measurement of the self-assembly process over a broad range of length- and timescales. The success of high-speed atomic force microscopy (HS-AFM) in imaging small scale mo ...

Excitonic channels from bio-inspired templated supramolecular assembly of J-aggregate nanowirest

Frank Nüesch, Jakob Heier, Surendra Babu Anantharaman

Supramolecular assemblies with controlled morphology are of paramount importance for energy transport in organic semiconductors. Despite considerable freedom in molecular design, the preparation of dyes that form one dimensional J-aggregates is challenging ...

Imaging cellular ultrastructures using expansion microscopy (U-ExM)

Michaël Unser, Paul Guichard, Davide Gambarotto, Virginie Hamel, Denis Fortun

Determining the structure and composition of macromolecular assemblies is a major challenge in biology. Here we describe ultrastructure expansion microscopy (U-ExM), an extension of expansion microscopy that allows the visualization of preserved ultrastruc ...

Interplay of H-Bonds with Aromatics in Isolated Complexes Identifies Isomeric Carbohydrates

Oleg Boyarkine, Ruslan Yamaletdinov, Vladimir Kopysov, Aleksandr Pereverzev

The tremendous isomeric diversity of carbohydrates enables a wide range of their biological functions but makes the identification and study of these molecules difficult. We investigated the ability of intermolecular interactions to communicate structural ...

Dynamic Nuclear Polarization Magic-Angle Spinning Nuclear Magnetic Resonance Combined with Molecular Dynamics Simulations Permits Detection of Order and Disorder in Viral Assemblies

David Lyndon Emsley, Marc Anthony Caporini

We report dynamic nuclear polarization (DNP)-enhanced magic-angle spinning (MAS) NMR spectroscopy in viral capsids from HIV-1 and bacteriophage AP205. Viruses regulate their life cycles and infectivity through modulation of their structures and dynamics. W ...

"Doubly Orthogonal" Labeling of Peptides and Proteins

Jérôme Waser, Beat Fierz, Nora Guidotti, Raphaël Michel Henri Simonet-Davin, Romain Gaëtan Tessier

Herein, we report a cysteine bioconjugation methodology for the introduction of hypervalent iodine compounds onto biomolecules. Ethynylbenziodoxolones (EBXs) engage thiols in small organic molecules and cysteine-containing peptides and proteins in a fast a ...

Single-molecule kinetics of pore assembly by the membrane attack complex

Georg Fantner, Adrian Pascal Nievergelt

The membrane attack complex (MAC) is a hetero-oligomeric protein assembly that kills pathogens by perforating their cell envelopes. The MAC is formed by sequential assembly of soluble complement proteins C5b, C6, C7, C8 and C9, but little is known about th ...

Synthesis and Characterization of Coordination Cages Based on Clathrochelate Metalloligands

Giacomo Cecot

The work presented in this thesis focused on the synthesis and characterization of new metalloligands based on iron(II) clathrochelate complexes. Clathrochelates can be functionalized peripherally with donor groups capable of coordinating metal ions. The s ...

Co-expression of CCT subunits hints at TRiC assembly

Oksana Andrei Sergeeva

The eukaryotic cytosolic chaperonin, t-complex polypeptide 1 (TCP-1) ring complex or TRiC, is responsible for folding a tenth of the proteins in the cell. TRiC is a double-ringed barrel with each ring composed of eight different CCT (chaperonin containing ...
