This is the promoter of the Escherichia coli yeaR/yoaG operon; responsive to nitrate, nitrite and nitric oxide.This is regulated mainly by phospho-NarL, although phospho-NarP can also activate it if NarL is not present. Repression of the promoter in the absence of nitrate/nitrite is mainly due to the repressor NsrR. Induction is higher under anaerobic conditions than under aerobic conditions, but strong induction still occurs under fully aerobic conditions. Unlike other E. coli promoters responding to nitrate and nitrite, this promoter is not repressed under aerobic conditions.

Summary

This is the promoter of the Escherichia coli yeaR/yoaG operon; responsive to nitrate, nitrite and nitric oxide.This is regulated mainly by phospho-NarL, although phospho-NarP can also activate it if NarL is not present. Repression of the promoter in the absence of nitrate/nitrite is mainly due to the repressor NsrR. Induction is higher under anaerobic conditions than under aerobic conditions, but strong induction still occurs under fully aerobic conditions. Unlike other E. coli promoters responding to nitrate and nitrite, this promoter is not repressed under aerobic conditions.
