Under aerobic conditions, phototrophic bacteria repress the formation of pigments to protect cells in the presence of light from the damaging effects of reactive oxygen species and consume oxygen through respiratory complexes. Members of the PpsR family regulate the transcription of bch, crt, puc, and hem genes in respond to redox or light conditions. This mini-review focuses on the function and distribution of PpsR proteins.
