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...
