In vitro antioxidant actions of sulfur-containing amino acids
, 2018 Sulfur-containing amino acids such as methionine, cysteine, and taurine are present in animals and plants with biological functions. The aim of this study was to determine the antioxidant activities of representative sulfur-containing amino acids using ...

resido: an R package for exploring amino acid residue composition of peptide and protein sequences
Frontiers in HorticultureAmino acid composition may be used in synthetic biology for fine-tuning amino acid content of plants to improve human or animal diets. One barrier to plant-based diet adoption is insufficiency of key amino acids such as methionine and lysine.

Alterations in Sulfur Amino Acids as Biomarkers of Disease [PDF]
The Journal of Nutrition, 2020 Homocysteine (Hcy) is methylated by methionine synthase to form methionine with methyl-cobalamin as a cofactor. The reaction demethylates 5-methyltetrahydrofolate to tetrahydrofolate, which is required for DNA and RNA synthesis. Deficiency of either of the cobalamin (Cbl) and/or folate cofactors results in elevated Hcy and megaloblastic anemia ...

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline
FEBS Open Bio, EarlyView.Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

Fluctuations of sulfate, S-bearing amino acids and magnesium in a giant clam shell [PDF]
Biogeosciences, 2014 We used micro-X-ray fluorescence combined with X-ray photoabsorption spectroscopy to investigate speciation-specific sulfur profiles in the inner shell layer of a giant clam (Hippopus hippopus).

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

The effect of storage on the amino acids composition in potato tubers
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 The aim of this study was to investigate the effect of storage duration on amino acids content in potato tubers. Tubers of six cultivars were stored for 16 weeks. Crude protein was determined by the Kjeldahl method.
