Insertional mutagenesis of a plasmid-borne Escherichia coli rpoB gene reveals alterations that inhibit beta-subunit assembly into RNA polymerase.
A plasmid was constructed that overproduces the Escherichia coli RNA polymerase beta subunit from a lac promoter-rpoB fusion. The overproduced, plasmid-encoded beta subunit assembled into functional RNA polymerase that supplied greater than 90% of the transcriptional capacity of the cells. Excess be...
