Control of the kilA gene of the broad-host-range plasmid RK2: involvement of korA, korB, and a new gene, korE.

abstract：:Insertional mutagenesis was conducted on Bacillus subtilis cells to screen for mutants resistant to catabolite repression. Three classes of mutants that were resistant to glucose-promoted but not mannitol-promoted catabolite repression were identified. Cloning and sequencing of the mutated genes revealed that the muta...
