Common NameSelenite
DescriptionThe selenite anion is a selenium oxoanion with the chemical formula SeO32−. A selenite (compound) is a compound that contains this ion. In slightly acid conditions, the hydrogenselenite ion, HSeO3−, is formed; in more acidic conditions selenous acid, H2SeO3, exists. Most selenite salts can be formed by heating the relevant metal oxide with selenium dioxide, e.g.:Na2O + SeO2 → Na2SeO3. Selenite is an inorganic form of selenium which may also be useful in cancer chemotherapy.(Wikipedia ).

Enzymes

Enzyme Details
1. Thioredoxin reductase 1, cytoplasmic
General function:
Involved in oxidoreductase activity
Specific function:
Isoform 1 may possess glutaredoxin activity as well as thioredoxin reductase activity and induces actin and tubulin polymerization, leading to formation of cell membrane protrusions. Isoform 4 enhances the transcriptional activity of estrogen receptors alpha and beta while isoform 5 enhances the transcriptional activity of the beta receptor only. Isoform 5 also mediates cell death induced by a combination of interferon-beta and retinoic acid.
Gene Name:
TXNRD1
Uniprot ID:
Q16881
Molecular weight:
70905.58
Reactions

3. Thioredoxin reductase 3
General function:
Involved in oxidoreductase activity
Specific function:
Displays thioredoxin reductase, glutaredoxin and glutathione reductase activities. Catalyzes disulfide bond isomerization. Promotes disulfide bond formation between GPX4 and various sperm proteins and may play a role in sperm maturation by promoting formation of sperm structural components (By similarity).
