Rubisco forms a lattice inside alpha-carboxysomes

The paper uses cryo electron tomography to image carboxysomes and reveals a novel lattice arrangement of Rubisco inside the microcompartment.

A new class of protein sensor links spirochete pleomorphism, persistence, and chemotaxis

The paper identifies a new protein sensor class (CheWS) in Treponema denticola that links spirochete morphology, persistence, and chemotaxis through SAM sensing.

Atypical chemoreceptor arrays accommodate high membrane curvature

This study identifies an alternative P2 symmetry in chemoreceptor arrays of Treponema denticola, adapted to high membrane curvature, revealing new structural features and functional roles of CheA and CheW-CheR-like proteins.

Repurposing a macromolecular machine: Architecture and evolution of the F7 chemosensory system

The paper traces the evolutionary origin of the F7 chemosensory system in E. coli by analyzing ancestral forms in related bacteria and identifying structural and functional changes.

Bacterial flagellar motor PL-ring disassembly sub-complexes are widespread and ancient

The paper shows that bacterial flagellar motor PL-ring sub-complexes persist after disassembly across multiple phyla and are ancient, not recently transferred.

Interdimer zipping in the chemoreceptor signaling domain revealed by molecular dynamics simulations

This study uses molecular dynamics simulations to reveal interdimer interactions in the Tsr chemoreceptor signaling domain, showing hydrophobic and electrostatic forces stabilize the trimer-of-dimers structure.

ETDB-Caltech: a blockchain-based distributed public database for electron tomography

The paper introduces a blockchain-based distributed database for storing and sharing electron tomography datasets, providing a user-friendly interface for data access and analysis.

Structure of the fission yeast actomyosin ring during constriction

This study uses cryo-electron tomography to image the 3D structure of the actomyosin ring in fission yeast during cell division, revealing the arrangement of actin filaments.
