Abstract excerpt
The OmpR protein is an activator specific for the E. coli ompC and ompF genes. This protein functions in a phosphorylation-dependent manner through a presumed interaction with RNA polymerase. In this study we isolated OmpR mutants which were suggested to be defective for transcriptional activatio...
