Mutational analysis of nitrate regulatory gene narL in Escherichia coli K-12.

Journal of bacteriology - 1 Jul 1991

Egan S M, Stewart V

Abstract excerpt

The narL gene product, NarL, is the nitrate-responsive regulator of anaerobic respiratory gene expression. We used genetic analysis of narL mutants to better understand the mechanism of NarL-mediated gene regulation. We selected and analyzed seven nitrate-independent narL mutants. Each of three independent, strongly constitutive mutants had changes of Val-88 to Ala. The other four mutants were weakly...
