Figure 7

Loss-of-function of thioredoxin reductase Trr1 results in constitutive oxidation of thioredoxins, which leads to suppression of mutation formation through two distinct mechanisms. Yap1 activation and consequent over-expression of Yap1-regulated oxido-reductases play a major role in reducing mutagenesis. TLS, translesion DNA synthesis.
