Enzymatic reduction and oxidation of fibre-bound azo-dyes [PDF]

, 2007
A new customer and environmental friendly method of hair bound dye decolouration was developed. Biotransformation of the azo-dyes Flame Orange and Ruby Red was studied using different oxidoreductases.

Complementary Muscle Metabolomics and Proteomics of Muscle in Cows With Post‐Calving Ketosis

Journal of Veterinary Internal Medicine, Volume 39, Issue 6, November/December 2025.
ABSTRACT Background The muscle tissue of dairy cows is a site of β‐hydroxybutyrate (BHBA) metabolism. The mechanisms underlying the changes in proteins and metabolites in the muscle tissue of cows with ketosis remain unclear. Objectives To elucidate the metabolic and physiological molecular adaptation mechanisms in the muscle tissue of cows with ...

Control of reactive intermediates in enzymes and enzyme complexes [PDF]

, 2018
Enzymes are the catalysts of life. They accelerate the rate of chemical reactions that would otherwise take longer than an organism’s lifetime to take just millisecond.

The Lrs14‐Like AbfR1 Homolog From Metallosphaera sedula Is a Nucleoid‐Organizing Protein

MicrobiologyOpen, Volume 14, Issue 5, October 2025.
Nucleoid organization in Crenarchaeota involves diverse small DNA‐binding proteins. The Lrs14‐type protein AbfR1 from Metallosphaera sedula binds nonsequence specifically across the genome and induces DNA condensation. These findings suggest a structural role for AbfR1Ms in chromatin architecture, functionally resembling bacterial nucleoid‐associated ...

Detection of reactive oxygen and nitrogen species by electron paramagnetic resonance (EPR) technique [PDF]

, 2017
During the last decade there has been growing interest in physical-chemical oxidation processes and the behavior of free radicals in living systems. Radicals are known as intermediate species in a variety of biochemical reactions.

Free Radicals in Health and Disease

MedComm, Volume 6, Issue 10, October 2025.
Free radicals have dual roles that can either selectively create oxidative damages to transformed cells in treating proliferative diseases such as cancers and some dermatological disorders or boost the antioxidant system in treating degenerative diseases such as neurodegenerative disorder, joint degeneration, and metabolic conditions.

Advances in ethanol production [PDF]

, 2011
Barriers to the commercialization of lignocellulosic ethanol include the development of more robust biocatalysts, reduction of cellulase costs, and high capital cost associated with a complex process.

Studies of the membrane‐bound flavocytochrome MsrQ flavin mononucleotide (FMN)‐binding site reveal an unexpected ubiquinone cofactor

The FEBS Journal, Volume 292, Issue 20, Page 5491-5505, October 2025.
The membrane‐bound heme flavoprotein MsrQ is the specific electron donor for the periplasmic methionine sulfoxide reductase MsrP. Analysis of its flavin environment revealed that ubiquinone (UQ) is a cofactor for MsrQ. However, redox studies demonstrate that UQ cannot function as an electron donor for the MsrPQ system.
