Thioredoxin plant
WebSep 11, 2024 · Abstract. In response to light, plants efficiently induce photosynthesis. Light activation of thiol enzymes by the thioredoxin (Trx) systems and cyclic electron transport by the PROTON GRADIENT REGULATION5 (PGR5)-dependent pathway contribute substantially to regulation of photosynthesis. WebIn plants, the thioredoxin system is particularly complex since at least 20 thioredoxin isoforms are found in the plant model Arabidopsis thaliana. Based upon primary …

WebMar 2, 2004 · Originally isolated from Escherichia coli in 1964 as an electron donor for ribonucleotide reductase (), thioredoxin is now known to play a role in a multitude of processes ().Apart from its oxidoreductase activity, thioredoxin exerts control over the activity of its target proteins via reversible thiol-disulfide exchange reactions (Fig. 2a).In … The primary function of Thioredoxin (Trx) is the reduction of oxidized cysteine residues and the cleavage of disulfide bonds. Multiple in vitro substrates for thioredoxin have been identified, including ribonuclease, choriogonadotropins, coagulation factors, glucocorticoid receptor, and insulin. Reduction of insulin is classically used as an activity test. The thioredoxins are maintained in their reduced state by the flavoenzyme thioredoxin reductase, in a NADPH-dependent reaction…
