An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Parallel computing of disturbance response instability theory of rockbursts

Meitan xuebao
At present, theoretical analyses of rockbursts have entered into the quantitative analysis stage from the qualitative analysis stage. The critical stress of the roadway surrounding rock has become the important basis for safe assessment of the roadway ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Critical bed shear stress and threshold of motion of maërl biogenic gravel

, 2014
A determination of the critical bed shear stress of maerl is a prerequisite for quantifying its mobility, rate of erosion and deposition in conservation management. The critical bed shear stress for incipient motion has been determined for the first time

Study on “zero coalburst” prevention and control in coalburst mines

Meitan xuebao
To address the safety needs of coalburst mines in China and fulfill the national “zero coalburst” management objectives of no casualties, no roadway damage, and no equipment damage, this study proposes the hierarchical prevention and control objectives ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Stress-sensitivity of coal fracture systems and its governing mechanism on permeability

Meitan xuebao
The investigation into the evolution mechanisms of fractures in high-stress-sensitive coal under external loading and their controlling effects on permeability is crucial for understanding gas migration in deep coal seams.
