The requirement of ArcA and Fnr for peak expression of the cyd operon in Escherichia coli under microaerobic conditions.

Molecular & general genetics : MGG - 1 Apr 1991

Fu H A, Iuchi S, Lin E C

Abstract excerpt

Transcriptional regulation of cyd, encoding the cytochrome d complex for O2 scavenging, was studied in Escherichia coli by monitoring phi(cyd-lac) expression under atmospheres containing 0-21% O2. Peak expression of this operon occurred under microaerobic conditions. Mutations in arcA (a trans-ac...
