Identification of proteins targeted by the thioredoxin superfamily in Plasmodium falciparum. [PDF]

, 2009
The malarial parasite Plasmodium falciparum possesses a functional thioredoxin and glutathione system comprising the dithiol-containing redox proteins thioredoxin (Trx) and glutaredoxin (Grx), as well as plasmoredoxin (Plrx), which is exclusively found ...

The Barley Grain Thioredoxin System – an Update

Frontiers in Plant Science, 2013
Thioredoxin reduces disulfide bonds and play numerous important functions in plants. In cereal seeds, cytosolic h-type thioredoxin facilitates the release of energy reserves during the germination process and is recycled by NADPH-dependent thioredoxin ...

Oxidized Forms of Ergothioneine Are Substrates for Mammalian Thioredoxin Reductase

Antioxidants, 2022
Ergothioneine (EGT) is a sulfur-containing amino acid analog that is biosynthesized in fungi and bacteria, accumulated in plants, and ingested by humans where it is concentrated in tissues under oxidative stress.

The Oxidized Protein Repair Enzymes Methionine Sulfoxide Reductases and Their Roles in Protecting against Oxidative Stress, in Ageing and in Regulating Protein Function

Antioxidants, 2018
Cysteine and methionine residues are the amino acids most sensitive to oxidation by reactive oxygen species. However, in contrast to other amino acids, certain cysteine and methionine oxidation products can be reduced within proteins by dedicated ...

One cysteine is enough: A monothiol Grx can functionally replace all cytosolic Trx and dithiol Grx

Redox Biology, 2020
Glutaredoxins are small proteins of the thioredoxin superfamily that are present throughout life. Most glutaredoxins fall into two major subfamilies.
