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.

DNA extraction for streamlined metagenomics of diverse environmental samples

BioTechniques, 2017
A major bottleneck for metagenomic sequencing is rapid and efficient DNA extraction. Here, we compare the extraction efficiencies of three magnetic bead−based platforms (KingFisher, epMotion, and Tecan) to a standardized column-based extraction platform ...

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

Effect of organic solvent on the extraction of lipids from krill powders using a one-step extraction process

Journal of Agriculture and Food Research
A variety of organic solvents were tested using a one-step extraction process to determine the extraction efficiencies and composition of lipids derived from krill powders. Extraction solvents tested included hexane (H), chloroform (C), methyl-tert-butyl

An ionic liquid extraction process for the separation of indole from wash oil

, 2015
Indole is an important industrial substance derived from wash oil, and the traditional alkali fusion method causes serious environmental problems. In this research, imidazolium-based ionic liquids (IBILs) were developed as new extraction agents to ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Field clean-up of crude oil spills on the coast of Ghana using Alcanivorax xenomutans Acinetobacter junii

Discover Environment
Oil spills are a persistent threat to marine ecosystems, particularly in regions with high shipping traffic such as Ghana’s coastline. Conventional crude oil cleanup methods often generate toxic by-products; making bioremediation a preferred alternative.
