pPepT: hypoxia-inducible promoter

pPepT, which is induced by hypoxia, is regulated by transcriptional activator: fumarate and nitrate reduction regulatory protein (FNR).[1]Under anaerobic conditions, FNR associates with [4Fe-4S]2+ clusters to form transcriptionally active homodimers, the dimer can bind DNA site-specifically and regulate transcription from target promoters. However, when the clusters are disrupted in the presence of oxygen, the FNR dimer dissociates into nonDNA-binding monomers. [2, 3]
