Nitrate regulation of anaerobic respiratory gene expression in narX deletion mutants of Escherichia coli K-12.

Journal of bacteriology - 1 Sept 1990

Egan S M, Stewart V

Abstract excerpt

Previous studies have shown that narL+ is required for nitrate regulation of anaerobic respiratory enzyme synthesis, including formate dehydrogenase-N, nitrate reductase, and fumarate reductase. Insertions in the closely linked narX gene decrease, but do not abolish, nitrate regulation of anaerobic enzyme synthesis. Analysis of sequence similarities suggests that NarX and NarL comprise a two-component regulatory...
