Protein
Redox-sensing transcriptional repressor Rex
Organism
Streptomyces coelicolor (strain ATCC BAA-471 / A3(2) / M145)
Function
Modulates transcription of respiratory genes in response to changes in cellular NADH/NAD(+) redox state. May play a general role as a sensor of cellular redox balance.
Similarity
Belongs to the transcriptional regulatory Rex family.
