Bio‐inspired Catalyst‐Modified Photocathode for Bias‐Free Photoelectrochemical NADH Regeneration
Advanced Science, Volume 12, Issue 8, February 24, 2025.Inspired by the structure and function of the thylakoid membrane and electron transport mediator function of Ferredoxin, a catalyst‐immobilized photocathode is constructed by self‐assembly of the aliphatic chain substituted [Rh(Cp*)(bpy)] molecules (Rh‐vi2+) and aliphatic chain decorated polythiophene semiconductors (PTTH), which can be coupled with a ...

Enzymatic and Enzyme‐Free Electrochemical Lactate Sensors: A Review of the Recent Developments
Electrochemical Science Advances, Volume 5, Issue 1, February 2025.ABSTRACT Lactate is a useful analytical indicator in various fields. The lactate monitoring benefits from evaluating the body's condition, as excessive muscle use or fatigue can result in injury. Further, it is useful for alerting to emergencies like haemorrhage, hypoxia, respiratory distress, and sepsis.

Star‐Like Polypeptides as Simplified Analogues of Horseradish Peroxidase (HRP) Metalloenzymes
Macromolecular Bioscience, Volume 24, Issue 10, October 2024.Peroxidases like HRP are powerful biocatalysts for oxidation reactions. Inspired by HRP, star‐shaped polypeptide analogues are synthesized via a grafting‐from approach, ring‐opening polymerization, and manganese porphyrins. These analogues exhibit enhanced resistance to denaturation and catalytic activity in oxidation reactions with H2O2.

Biomimetic models for redox enzyme systems [PDF]
, 2009 Supramolecular chemistry involves the study of noncovalent interactions that take place between molecules. A supramolecule or host-guest complex is formed when a noncovalent binding or complexation event occurs between two such molecules. Hydrogen bonds,

FEBS Letters, Volume 598, Issue 14, Page 1692-1714, July 2024.Traditional views of oxygen's role in evolution focus on improved energy yield in heterotrophic pathways. Before respiratory terminal oxidases arose, however, oxygen potently inhibited anaerobic growth, often by degrading FeS clusters. Several pathways for essential cofactors include enzymes with FeS clusters, selecting for alternative, oxygen‐tolerant

The extracellular peroxygenase of the agaric fungus Agrocybe aegerita: catalytic properties and physiological background with particular emphasis on ether cleavage [PDF]
, 2010 Litter-decay fungi have recently been shown to secrete heme-thiolate peroxygenases that oxidize various organic chemicals, but little is known about the physiological role or the mechanism of these enzymes. The aromatic peroxygenase of Agrocybe aegerita (
