physiological function | a double knockout mutant lacking NtrC and sulfiredoxin shows a phenotype similar to the NtrC mutant, while the sulfiredoxin mutant resembles wild-type plants. The deficiency of NtrC causes reduced overoxidation of 2-Cys peroxiredoxins, whereas the deficiency of sulfiredoxin has the opposite effect. The disulfide bond linking the resolving and peroxidatic cysteines protects the latter from overoxidation. The overoxidation of chloroplast 2-Cys peroxiredoxins shows no circadian oscillation. The low level of 2-Cys peroxiredoxin overoxidation in the NtrC mutant is light dependent | Arabidopsis thaliana |
