Overlapping promoters modulate Fnr- and ArcA-dependent anaerobic transcriptional activation of the focApfl operon in Escherichia coli.

Microbiology (Reading, England) - 1 Mar 1997

Kaiser Manuela, Sawers Gary

Abstract excerpt

The recently identified P6A promoter of the anaerobically inducible focApfl operon of Escherichia coll overlaps the Fnr (fumarate-nitrate reduction regulator)-dependent P6 promoter. The Fnr-binding site of P6 and the -35 hexamer sequence of P6A are shared between the promoters. Inactivation of P6A, through introduction of a -10 hexamer mutation, resulted in enhanced anaerobic induction of operon expression. The...
