The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

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 ...

Contribution of different electron-capture mechanisms in the fragmentation of CO upon slow ion-molecule collisions

New Journal of Physics
We present a recoil ion—projectile ion coincidence study on the three body fragmentation of $\mathrm{CO_2^{3+}}$ ion into $\mathrm{C^+ + O^+ + O^+}$ fragments upon impact with $\mathrm{Ar^{3+},~Ar^{6+}~and~Ar^{8+}}$ projectile ions having the same ...

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

Potential energy curves and spectroscopic properties of the low-lying states of CaH molecule

四川大学学报. 自然科学版, 2020
The potential energy curves (PECs) of the 10 low-lying states of calcium monohydride (CaH) have been calculated using the internally contracted multi-reference configuration interaction plus Davidson modification (icMRCI+Q) approach with core-valence ...
