Abstract excerpt
The nfo (endonuclease IV) gene of Escherichia coli is induced by superoxide generators such as paraquat (methyl viologen). An nfo'-lacZ operon fusion was used to isolate extragenic mutations affecting its expression. The mutations also affected the expression of glucose 6-phosphate dehydrogenase, Mn2(+)-superoxide dismutase (sodA), and three lacZ fusions to soi (superoxide-inducible) genes of unknown function....
