CC   -!- FUNCTION: Negative regulator of the carotenoid synthesis regulon. It is
CC       probably inactivated by protoporphyrin IX in the presence of blue
CC       light. Inactivation of CarR leads to loss of negative control over the
CC       carotenogenesis protein CarQ.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC   -!- INDUCTION: By light.
