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.

Digestion of Milk from Red Chittagong Cattle Focusing Proteolysis and Lipolysis [PDF]

Asian-Australasian Journal of Animal Sciences, 2015
Ex vivo digestion of proteins and fat in Red Chittagong Cattle milk from Bangladesh was carried out using human gastrointestinal enzymes. This was done to investigate the protein digestion in this bovine breed’s milk with an especial focus on the ...

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.

Domino Synthesis of Benzo-fused β,γ-Unsaturated Ketones from Alkenylboronic acids and N-Tosylhydrazone-tethered Benzonitriles [PDF]

, 2019
The transition-metal-free domino reaction between alkenylboronic acids and N-tosylhydrazones from o-(2-oxoalkyl)- and o-(3-oxoalkyl)benzonitriles leads to β,γ-unsaturated indanones and tetralones featuring an α-“all-carbon” quaternary center.

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 ...

Ribosomal Incorporation of Consecutive β‑Amino Acids

, 2018
Due to their unique characteristics, which are not shared by canonical α-peptides, peptides that contain stretches of consecutive β-amino acids are attractive scaffolds for novel peptide drugs and nanomaterials. Although ribosomal incorporation of single

Enantioselective decarboxylative chlorination of β-ketocarboxylic acids

Nature Communications, 2017
Due to the synthetic utility of the products, stereoselective halogenation is a powerful method for the synthesis of chiral compounds. Here the authors report an enantioselective decarboxylative chlorination, giving access to a range of α-chloroketones.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
