Organism
Streptomyces coelicolor (strain ATCC BAA-471 / A3(2) / M145)
Function
Component of the thioredoxin-thioredoxin reductase system. Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. Stimulates complex formation between sigma factor SigR and its cognate anti-sigma factor RsrA probably by reducing RsrA.
Similarity
Belongs to the thioredoxin family.
