Evaluating the similarity of biochemical reactions and its uses for mapping novel and orphan reactions to protein sequences

Recent advances in synthetic biochemistry have resulted in a wealth of de novo hypothetical enzymatic reactions that are not matched to protein-encoding genes, deeming them “orphan”. Nearly half of known metabolic enzymes are also orphan, leaving important ...

Inferring interaction partners from protein sequences using mutual information

Anne-Florence Raphaëlle Bitbol

Functional protein-protein interactions are crucial in most cellular processes. They enable multi-protein complexes to assemble and to remain stable, and they allow signal transduction in various pathways. Functional interactions between proteins result in ...

Multicolor single-particle reconstruction of protein complexes

Pierre Gönczy, Suliana Manley, Kyle Michael Douglass, Christian Sieben, Niccolo Banterle

Single-particle reconstruction (SPR) from electron microscopy (EM) images is widely used in structural biology, but it lacks direct information on protein identity. To address this limitation, we developed a computational and analytical framework that reco ...

Structural and functional analysis of host attachment proteins from contractile injection systems

Michel Plattner

Bacteriophages of the myoviridae family, R-type pyocin, Photorhabus virulence cassette (PVC), Serratia antifeeding prophage (Afp) and type 6 secretion system (T6SS) form a class of contractile injection systems that share common structural and functional c ...

Toward a unified scoring function for native state discrimination and drug-binding pocket recognition

Stefano Zamuner

Protein folding and receptor–ligand recognition are fundamental processes for any living organism. Although folding and ligand recognition are based on the same chemistry, the existing empirical scoring functions target just one problem: predicting the cor ...

Unintended specificity of an engineered ligand-binding protein facilitated by unpredicted plasticity of the protein fold

Kai Johnsson, Alberto Schena

Attempts to create novel ligand-binding proteins often focus on formation of a binding pocket with shape complementarity against the desired ligand (particularly for compounds that lack distinct polar moieties). Although designed proteins often exhibit bin ...

Rosetta FunFolDes - A general framework for the computational design of functional proteins

Bruno Emanuel Ferreira De Sousa Correia, Andreas Scheck, Jaume Bonet Martinez, Fabian Sesterhenn, Stéphane Rosset, Che Yang, Sarah Wehrle, Freyr Sverrisson, Sabrina Susan Vollers, Mélanie Evelyne Villard, Anne Marie-Thérèse Suzanne Billet, Roxanne Marine Lourman, Karen Schriever

The robust computational design of functional proteins has the potential to deeply impact translational research and broaden our understanding of the determinants of protein function and stability. The low success rates of computational design protocols an ...

The cold denaturation of IscU highlights structure–function dualism in marginally stable proteins

Paolo De Los Rios

Proteins undergo both cold and heat denaturation, but often cold denaturation cannot be detected because it occurs at temperatures below water freezing. Proteins undergoing detectable cold as well as heat denaturation yield a reliable curve of protein stab ...

Palmitoylation mediates membrane association of hepatitis E virus ORF3 protein and is required for infectious particle secretion

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Johann Mauron, Joël Oppliger, Maxime Matter, Noémie Oechslin

Hepatitis E virus (HEV) is a positive-strand RNA virus encoding 3 open reading frames (ORF). HEV ORF3 protein is a small, hitherto poorly characterized protein involved in viral particle secretion and possibly other functions. Here, we show that HEV ORF3 p ...

Characterization of the predicted membrane anchor of reductive dehalogenases

Julien Maillard, Lorenzo Cimmino, Marie Joanna Marie-Joseph Dannay

BACKGROUND Organohalide respiration (OHR) is a metabolic process that couples the reduction of halogenated organic compounds to energy conservation in a few phylogenetically diverse anaerobic bacteria. In this study, tetrachloroethene (= perchloroethene, P ...
