Algorithmic Identification of Murzymes and Murburn Mechanisms Based on Structural, Theoretical, Experimental, and Generic Features

BioMed Research International, Volume 2026, Issue 1, 2026.
Murburn concept is a decade‐old theorization for explaining several cellular redox‐metabolic and electro/mechanophysiological outcomes. It stems from “mured burning”, connoting delocalized stochastic electron‐transfer processes, involving diffusible reactive species (DRS).

Genome-wide structural and evolutionary analysis of the P450 monooxygenase genes (P450ome) in the white rot fungus Phanerochaete chrysosporium : Evidence for gene duplications and extensive gene clustering

BMC Genomics, 2005
Background Phanerochaete chrysosporium, the model white rot basidiomycetous fungus, has the extraordinary ability to mineralize (to CO2) lignin and detoxify a variety of chemical pollutants.

Quantitative Treatments for Explaining the Mechanism and Kinetics of Catalytic Electron Transfers in Murburn Processes, Particularly Involving Heme Enzymes Like (Per)oxidases and P450s

BioMed Research International, Volume 2026, Issue 1, 2026.
The seminal Michaelis–Menten theorization for biological catalysis was based on “transition state” (TS), involving the formation of a topologically complementary substrate (S) and enzyme (E) complex (ES) at the “active site” of the latter. Rudolph Marcus put forth the theory of outer sphere electron transfer (ET) in a “donor–acceptor” TS complex, which

Recent Advances in Electrochemical Sensing Approaches for Nitrite Monitoring in Environmental Applications

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Electrochemical sensing of nitrite has attracted considerable attention in recent years owing to its importance in environmental monitoring, food safety, and healthcare. Nitrite, widely used as a food preservative and corrosion inhibitor, poses significant health risks, including carcinogenicity and teratogenicity, when present at elevated ...

Nitric Oxide Binding Geometry in Heme-Proteins: Relevance for Signal Transduction

Antioxidants
Nitric oxide (NO) synthesis, signaling, and scavenging is associated to relevant physiological and pathological events. In all tissues and organs, NO levels and related functions are regulated at different levels, with heme proteins playing pivotal roles.

Biomimetic chemistry of hemeproteins.

The Keio Journal of Medicine, 1989
Hemeproteins play important physiological roles for an oxygen metabolism in living organisms. Their functions are divided to three main groups, i) hemoglobins, myoglobins and the cytochromes which function by transporting and storing dioxygen and electrons; ii) catalase and peroxidases which are activated by hydrogen peroxide, iii) cytochrome oxidase ...

Acetylated Epigallocatechin Gallate and Ascorbyl Palmitate: Comparative Study on Antioxidant Activity and Retardation of Lipid Oxidation in Fish Mince and Shrimp Oil

Journal of Food Science, Volume 90, Issue 10, October 2025.
ABSTRACT Antioxidant activities of acetylated epigallocatechin gallate (A‐EGCG) and ascorbyl palmitate (AP) were compared using different in vitro assays and food model systems. Both A‐EGCG and AP exhibited DPPH and ABTS radical scavenging activities and reducing power. AP demonstrated greater scavenging efficacy toward both radicals than A‐EGCG (p < 0.

The Urea Cycle in Connection to Polyamine Metabolism in Higher Plants: New Perspectives on a Central Pathway

Physiologia Plantarum, Volume 177, Issue 3, May/June 2025.
ABSTRACT The ornithine‐urea cycle is a biochemical pathway primarily found in animals, where it plays a crucial role in the re‐assimilation of ammonium and the removal of excess nitrogen in the form of urea. In lower photosynthetic eukaryotes, it contributes to metabolic responses during episodes of high nitrogen availability.

Development of Bioorthogonally Degradable Tough Hydrogels Using Enamine N‐Oxide Based Crosslinkers

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Inducibly degradable enamine N‐oxide crosslinkers are integrated into tough double network hydrogels, enabling rapid and bioorthogonal degradation by aqueous diboron solutions. These chemical reagent‐responsive biomaterials maintain structural integrity during use while enabling rapid degradation when needed, making them ideal for applications in ...

Evolutionary Pro‐To‐Thr Mutation in the Intrinsically Disordered Domain of ANP32 Family Members Modulates Their Target Binding Modes

Advanced Science, Volume 12, Issue 12, March 27, 2025.
Protein evolution usually lies on mutations at disordered domains to promote novel functions and regulations. Here it is demonstrated that this is the case of ANP32A and ANP32B, two paralogs with apparently similar structures and functions, where a single amino‐acid substitution in the disordered domain triggers the extended‐to‐compact conformational ...
