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 encodes a 357-amino-acid protein. Analysis of a defined chrR null mutation indicated that this protein positively...
