Chemomimetic biocatalysis: exploiting the synthetic potential of cofactor-dependent enzymes to create new catalysts.

Journal of the American Chemical Society, 2015
Despite the astonishing breadth of enzymes in nature, no enzymes are known for many of the valuable catalytic transformations discovered by chemists. Recent work in enzyme design and evolution, however, gives us good reason to think that this will change.

Plasma‐Treated Hydrogel for Combined RONS and Chemotherapy Delivery: A Proof‐of‐Concept In Ovo

Advanced Functional Materials, EarlyView.
This study explores plasma‐treated hydrogels (PTH) as a new way to deliver both reactive oxygen and nitrogen species and chemotherapy (Doxorubicin) directly to tumors. In ovo tests show effects after a single dose, especially in osteosarcoma tumors. Tumor weight decrease, and a resistance‐related protein is reduced.

Engineering a Single Amino Acid Bionanozyme for Ultrasensitive Detection of Biomarkers: A WHO‐REASSURE‐ Aligned Approach

Advanced Functional Materials, EarlyView.
A unique 2D bionanozyme, engineered from a single amino acid and copper ions, demonstrates peroxidase‐mimicking catalytic activity. This efficient and simple bionanozyme allows for ultrasensitive, equipment‐free visual detection of key biomarkers in both test and real samples, meeting the WHO‐REASSURE standards for practical diagnostic applications ...

CASCADE: high-throughput characterization of regulatory complex binding altered by non-coding variants

Cell Genomics, 2022
Summary: Non-coding DNA variants (NCVs) impact gene expression by altering binding sites for regulatory complexes. New high-throughput methods are needed to characterize the impact of NCVs on regulatory complexes.

Covalently bound substrate at the regulatory site triggers allosteric enzyme activation [PDF]

, 2008
The mechanism by which the enzyme pyruvate decarboxylase from yeast is activated allosterically has been elucidated. A total of seven three-dimensional structures of the enzyme, of enzyme variants or of enzyme complexes form two yeast species (three of ...

An Animal‐Free Patient‐Derived Tissue‐Mimetic Biochip Model of the Human Synovial Membrane for Human‐Relevant Osteoarthritis Research

Advanced Healthcare Materials, EarlyView.
Reihs et al. present the development of a humanized, animal‐free synovial membrane model for osteoarthritis. Methods include 3D biochip cultures of human‐primary OA synoviocytes with matrix and serum surrogates. Results show replication of synovial architecture and increased Yap1 expression.

The Fe–V Cofactor of Vanadium Nitrogenase Contains an Interstitial Carbon Atom

Angewandte Chemie, 2015
The first direct evidence is provided for the presence of an interstitial carbide in the Fe–V cofactor of Azotobacter vinelandii vanadium nitrogenase. As for our identification of the central carbide in the Fe–Mo cofactor, we employed Fe Kβ valence-to ...

Overcoming barriers for investigating nickel-pincer nucleotide cofactor-related enzymes

mBio
The nickel-pincer nucleotide (NPN) cofactor is a modified pyridinium mononucleotide that tri-coordinates nickel and is crucial for the activity of certain racemases and epimerases. LarB, LarC, and LarE are responsible for NPN synthesis, with the cofactor
