Mutations in the alpha subunit of RNA polymerase that affect the regulation of porin gene transcription in Escherichia coli K-12.

Journal of bacteriology - 1 Sept 1993

Sharif T R, Igo M M

Abstract excerpt

The two-component regulatory system consisting of OmpR and EnvZ controls the differential expression of major outer membrane porin proteins OmpF and OmpC of Escherichia coli K-12. We have isolated and characterized two mutations in rpoA, the gene encoding the alpha subunit of RNA polymerase, that decrease the expression of OmpF. These mutations have a number of properties that distinguish them from previously...
