Regulation of narK gene expression in Escherichia coli in response to anaerobiosis, nitrate, iron, and molybdenum.

Journal of bacteriology - 1 Nov 1992

Kolesnikow T, Schröder I, Gunsalus R P

Abstract excerpt

The regulation of the narK gene in Escherichia coli was studied by constructing narK-lacZ gene and operon fusions and analyzing their expression in various mutant strains in response to changes in cell growth conditions. Expression of narK-lacZ was induced 110-fold by a shift to anaerobic growth and a further 8-fold by the presence of nitrate. The fnr gene product mediates this anaerobic response, while nitrate...
