Abstract

In facultative anaerobes, the anaerobic expression of respiratory genes is regulated by a transcriptional activator, FNR. Transcription in vitro of the E. coli fnr gene was repressed by its product, FNR. The transcription of the E. coli nar X gene encoding the nitrate sensor protein was likewise repressed. DNA truncation experiments for fnr and nar X genes indicated that multiple anaero-boxes in each promoter region are essential for repression by the FNR protein, but they also suggest that factor-independent upstream activation signals are operating with these promoters.
