Putative FAD-dependent oxidoreductase involved in the resistance to cercosporin and other singlet oxygen-generating photosensitizers. Translocates from mitochondria to the nucleus under apoptotic conditions, where it degrades DNA and induces apoptosis (By similarity). Binds 1 [2Fe-2S] cluster. Translocates from mitochondrion to the nucleus upon apoptosis induction. Present with 1560 molecules/cell in log phase SD medium. Belongs to the FAD-dependent oxidoreductase family.
