Structural characterization of the Pseudomonas Aeruginosa MexR-mexR repressor-operator complex: a small-angle X-ray and neutron scattering perspective

This study characterizes the structure of the MexR-mexR repressor-operator complex using SAXS and SANS, revealing DNA bending and flexibility between binding sites.

Beyond a unitary construct: Dissecting stopping behaviour in two bird species

This study examines stopping behaviour in two gull species using three tasks, finding species-specific differences linked to migration and foraging strategies.

Biophysical characterization of calcium-binding and modulatory-domain dynamics in a pentameric ligand-gated ion channel

This study characterizes the structural dynamics of the calcium-sensitive channel DeCLIC using cryo-EM, SANS, and MD simulations, revealing conformational flexibility in the NTD and calcium binding site.

Human myelin proteolipid protein structure and lipid bilayer stacking

This study determines the structure of human myelin proteolipid protein (PLP) and its isoform DM20, revealing their dimeric conformation and role in membrane stacking and organization.

Caenorhabditis nematodes colonize ephemeral resource patches in neotropical forests.

The paper investigates Caenorhabditis nematode species composition and colonization dynamics in tropical forests, finding globally distributed androdiecious species dominate and colonization occurs via phoresy with low founder numbers.

Metaeffector interactions modulate the type III effector-triggered immunity load of Pseudomonas syringae

This study identifies metaeffector interactions that suppress Effector-Triggered Immunity (ETI) in Pseudomonas syringae, revealing how these interactions help the pathogen evade plant immune responses.

Mg2+-dependent conformational equilibria in CorA: an integrated view on transport regulation

This study investigates the conformational dynamics of CorA, revealing Mg2+-dependent conformational equilibria and dynamic behavior through SANS, MD simulations, and NMR.

Probing solution structure of the pentameric ligand-gated ion channel GLIC by small-angle neutron scattering

This study uses small-angle neutron scattering to examine conformational changes in the bacterial ion channel GLIC under resting and activating conditions, finding no evidence for divergent mechanisms.

Host-pathogen co-existence incurs reproductive costs

This study shows that host-pathogen co-existence in pigeons leads to reduced reproductive success but protects against clinical disease.

Toxigenic and zoonotic Corynebacterium ulcerans emerges from widespread hedgehog disease

The paper isolates toxin-producing Corynebacterium ulcerans from diseased hedgehogs in Belgium, highlighting strain diversity and low antimicrobial resistance.

Body size and tree species composition determine variation in prey consumption in a forest-inhabiting generalist predator

This study shows that body size and tree species composition influence prey consumption in orb-weaving spiders, with larger spiders consuming larger prey and tree diversity affecting prey richness.

Structural Studies of Overlapping Dinucleosomes in Solution

The paper investigates the solution structure of overlapping dinucleosomes using SAXS, SANS, modeling, and simulations, showing histone tails stabilize their conformations.

PSX: Protein-Solvent Exchange - Software for calculation of deuterium-exchange effects in SANS measurements from protein coordinates

The paper introduces PSX, a software tool for calculating deuterium-exchange effects in SANS measurements from protein coordinates, showing that the common 90% exchange assumption is often an overestimate.

Molecular Evolution of Pseudomonas syringae Type III Secreted Effector Proteins

The paper analyzes T3SE variation across 494 P. syringae strains, identifying 14,613 T3SEs and showing significant diversity and positive selection within families.
