Thioredoxins
WebAbstract Since their discovery as a substrate for ribonucleotide reductase (RNR), the role of thioredoxin (Trx) and glutaredoxin (Grx) has been largely extended through their regulatory function. Both proteins act by changing the structure and activity of a broad spectrum of target proteins, typically by modifying redox status. WebPlastidial Thioredoxins. The sequencing of the genome of Arabidopsis thaliana revealed that this plant contained numerous isoforms of thioredoxin (Trx), a protein involved in thiol-disulfide exchanges. On the basis of sequence comparison, seven putative chloroplastic Trxs have been identified, four belonging to the m -type, two belonging to the ...
Thioredoxins
Did you know?
Thioredoxins are small disulfide-containing redox proteins that have been found in all the kingdoms of living organisms. Thioredoxin serves as a general protein disulfide oxidoreductase. It interacts with a broad range of proteins by a redox mechanism based on reversible oxidation of 2 cysteine thiol groups to a disulfide, accompanied by the transfer of 2 electrons and 2 protons. The net result is the covalent interconversion of a disulfide and a dithiol. WebMar 30, 2024 · Delineating quiescence and dormancy. Quiescence (noun) is a labile state of a cell, embryonic or meristematic structure, where division of the cell or cell population is repressed by non-cell-autonomous processes. Cell division may not have ceased or stalled, and evidence suggests that mitosis continues even in stem cell populations.
Thioredoxin is a class of small redox proteins known to be present in all organisms. It plays a role in many important biological processes, including redox signaling. In humans, thioredoxins are encoded by TXN and TXN2 genes.
