The Journal of Physiology, EarlyView.Abstract figure legend Three weeks of overtraining in trained endurance athletes reduced exercise performance without impairing glucose tolerance. In skeletal muscle, overtraining was associated with increased expression of lipid metabolism‐related proteins, enhanced mitochondrial biogenesis and preserved insulin signalling, despite elevated oxidative ...

New Phytologist, Volume 252, Issue 4, Page 1376-1395, November 2026.Osmotic stressors induce developmental and physiological changes in rice (Oryza sativa) seedlings, which are modulated by cell‐type‐specific gene expression and regulatory networks. We exposed plants to two levels of drought and salinity stress and measured the effects of these stressors on developing leaves by measuring physiological traits, ion ...

Methionine sulfoxide reductases of Aspergillus nidulans [PDF]
, 2014 Methionine sulfoxide reductases (Msr) are repair proteins, which provide an important part of the cellular antioxidant defense. Methionine oxidation results in a diasteromeric mixture of methionine-S-sulfoxide (Met-S-O) and methionine-R-sulfoxide (Met-R ...

Diversity of protein and mRNA forms of mammalian methionine sulfoxide reductase B1 due to intronization and protein processing. [PDF]
PLoS ONE, 2010 Methionine sulfoxide reductases (Msrs) are repair enzymes that protect proteins from oxidative stress by catalyzing stereospecific reduction of oxidized methionine residues.

One Hundred Years of Sulfido Ligand in the Molybdenum Cofactor: New Perspectives
ChemBioChem, Volume 27, Issue 19, 14 October 2026.The terminal sulfido ligand in mononuclear molybdoenzymes has been appreciated for almost 125 years, with the characterization of Schardinger's enzyme in cow's milk, now known to be xanthine oxidase, that was isolated in 1902 in Vienna, Austria. The ligand is found in molybdoenzymes identified across all kingdoms of life.

Unraveling the specificities of the different human methionine sulfoxide reductases
, 2014 The oxidation of free and protein-bound methionine into methionine sulfoxide is a frequently occurring modification caused by ROS. Most organisms express methionine sulfoxide reductases (MSR enzymes) to repair this potentially damaging modification ...
