Study of redox-regulated transcription factors in prokaryotes.

Abstract

Several prokaryotic regulatory proteins that respond to changes in oxygen tension or the presence of oxidative agents have now been identified. The Fnr protein governs the expression of numerous genes during anaerobic growth, both as a transcriptional activator and as a repressor. OxyR protein responds to cellular exposure to H2O2 to stimulate transcription… (More)
