ChrR positively regulates transcription of the Rhodobacter sphaeroides cytochrome c2 gene.
Journal of bacteriology - 1 Apr 1995
Schilke B A, Donohue T J
Abstract excerpt
Transcription of the Rhodobacter sphaeroides cytochrome c2 gene (cycA) is negatively regulated by both the presence of oxygen and intermediates in tetrapyrrole biosynthesis. A mutation responsible for uncoupling cycA transcription from tetrapyrrole availability was localized to a gene (chrR) that...
