Abstract excerpt
Insertion and deletion mutagenesis of the leader region of the Bacillus subtilis rib operon encoding FMN-specific sensor RNA was conducted. Insertions of different structure and length in the conservative motif of the leader sequence (Rfn-element) were shown to cause partially constitutive expression of the operon resulted in an increased accumulation of riboflavin. At the same time, introducing into the genome...
