Abstract

The expression of bacterial operons encoding nitrite reductase is controlled at the level of transcription initiation by four factors: oxygen, nitrite ions, nitrate ions and glucose. We propose to use a combination of biochemical and genetic approaches to discover how signals from these different metabolites are integrated at the promoters of the Escherichia coli nir genes, encoding NADH-dependent nitrite reductase, and the E. coli nrf genes, encoding formate-dependent nitrite reductase. This will provide an important paradigm for understanding the mechanism by which diverse signals interact at promoters to regulate cellular responses to environmental changes.
