A nar-lac operon fusion was used to isolate a mutant in which the expression of the nar operon was no longer repressed by oxygen. The nard mutation, located upstream of the nar structural genes, was found to be cis dominant; it led to independence from the Fnr protein which, in the wild-type strain, exerts a strict positive control on the nar operon. Both other known controls, nitrate induction and autoregulation, were unaffected. It is proposed that molecular oxygen controls the expression of nar via Fnr and that the nard mutation affects the Fnr binding site of the narGHI control region.
