The SPFH complex HflK-HflC regulates aerobic respiration in bacteria

This study identifies the HflK-HflC complex as essential for aerobic respiration in E. coli by regulating IspG abundance and ubiquinone levels.

Physics and physiology determine strategies of bacterial investment in flagellar motility

The paper shows that bacterial investment in flagellar motility is constrained by hydrodynamics and fitness costs, with E. coli strains maximizing motility under nutrient-rich conditions.

Enhanced metabolic entanglement emerges during the evolution of an interkingdom microbial community

This study evolves an engineered microbial community to show how metabolic interactions increase, leading to interdependence and indirect selection for mutualism.

Experimental evolution of a reduced bacterial chemotaxis network

This study uses experimental evolution to test the necessity of chemotaxis pathway components in E. coli, finding that core components are essential but some auxiliary proteins can be compensated for.

Systematic mapping of chemoreceptor specificities for Pseudomonas aeruginosa

This paper systematically identifies and characterizes chemoeffectors for Pseudomonas aeruginosa using a combination of in vivo and in vitro methods.

Regulation by cyclic-di-GMP attenuates dynamics and enhances robustness of bimodal curli gene activation in Escherichia coli

This study shows that c-di-GMP regulation modulates bimodal curli gene activation in E. coli by affecting its dynamics and robustness, without being required for its emergence.

Dependence of diffusion in Escherichia coli cytoplasm on protein size, environmental conditions and cell growth

The paper investigates protein diffusion in E. coli cytoplasm using FCS and models, finding that diffusion depends on protein size, environmental conditions, and cell growth, with viscosity changes affecting all sizes proportionally.

Functional determinants of a small protein repressor controlling a broadly conserved bacterial sensor kinase

This study investigates how mutations in MgrB affect its ability to inhibit PhoQ, revealing key residues and regions critical for its function.

The protein architecture of the endocytic coat analyzed by FRET

This study uses FRET microscopy to map the nanoscale organization of the endocytic coat in yeast, revealing its stratified structure and functional layers.

Chemotactic behavior of Escherichia coli at high cell density

This study investigates how high cell density affects chemotactic behavior in Escherichia coli, finding that collective motion suppresses chemotaxis at higher densities.

BiofilmQ, a software tool for quantitative image analysis of microbial biofilm communities

BiofilmQ is a software tool that enables automated, high-throughput quantitative analysis of 3D and 2D microbial biofilm communities through image cytometry.

Self-Organisation And Positioning Of Bacterial Protein Clusters

The paper presents a model for self-organization and positioning of dynamic bacterial protein clusters using a phase-locked Turing pattern, explaining regular positioning of SMC complexes on the nucleoid.
