Requirement of Fnr and NarL functions for nitrate reductase expression in Escherichia coli K-12.

RESUMO
I used a chlC-lac operon fusion to study regulatory mutations which affect nitrate reductase expression in Escherichia coli. A NarL- mutant apparently lacks a nitrate-specific positive regulatory component. Furthermore, an fnr (nirR) mutation prevented enzyme induction under any conditions. These data are consistent with a two-step, positive control model for nitrate reductase regulation.
