Solvent Channels and Electric Fields Guide Proton Delivery to the Active Site of Heme Peroxidases

Angewandte Chemie, Volume 137, Issue 50, December 8, 2025.
Electrostatic potential surfaces and electric field lines reveal that local fields guide proton delivery through multiple conserved solvent channels in heme peroxidases, enabling efficient access to the active site. Abstract The active sites of heme enzymes have evolved to control the formation of highly reactive intermediates in oxidative catalysis ...

Degradation of pigments in Limnospira platensis extracts

Journal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4426-4438, May 2026.
Abstract BACKGROUND Limnospira platensis, commonly known as spirulina, holds promise for application as a food ingredient and nutraceutical due to its rich protein and antioxidant content, including chlorophylls, carotenoids and phycocyanin. Despite its potential, the vibrant colour poses a challenge for consumer acceptance, hampering the marketability

Generation and modulation of catalytically relevant states of a dye‐decolourizing peroxidase using time‐resolved serial femtosecond crystallography with drop‐on‐chip mixing and X‐ray‐driven reduction

Acta Crystallographica Section D, Volume 82, Issue 5, Page 434-445, May 2026.
We characterize the formation of a ferryl state of a dye‐decolourizing peroxidase by drop‐on‐chip serial femtosecond crystallography and also the modulation of the heme redox state using dose‐resolved serial synchrotron crystallography.Metalloenzymes containing a heme cofactor catalyse a wide range of oxidative reactions critical to life. Understanding

Covalent Immobilization of Laccase on Mesoporous Bismuth Silicate for High‐Performance Biodegradation of Contaminants

European Journal of Inorganic Chemistry, Volume 29, Issue 10, 1 April 2026.
Myceliophthora thermophila laccase covalently immobilized on bismuth silicate (BiSi‐ext) achieved synergistic adsorption–biodegradation of Tectilon Blue 4R‐01 and ibuprofen. The biocatalyst showed enhanced stability, reusability, and rapid pollutant removal via expanded active‐site accessibility, enabling efficient, eco‐friendly wastewater remediation.

Degradation of Dyes by Fungi: A Bibliometric Study and Bibliographic Review

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT The degradation of dyes from textile effluents is considered a major challenge due to their high potential for environmental contamination and health risks due to their toxicity. In this sense, the use of fungi for the degradation of these compounds is reported in the literature as an ecological alternative with great potential.
