title: [Cloning the operon genes of riboflavin biosynthesis in Bacillus subtilis on plasmid vector pBR322 in Escherichia coli].
abstract: The operon for riboflavine biosynthesis of Bacillus subtilis wild type and its operator-constitutive derivative have been cloned in Escherichia coli cells on the plasmid pBR322 vector. The plasmids constructed were able to transform strains of E. coli and Bac. subtilis from Rib- to Rib+ phenotype. A DNA insert into the EcoRI site of pBR322 causes a decrease in tetracycline gene expression. The operator of the riboflavine operon of Bac. subtilis does not participate in regulation of the operon expression in E. coli cells.
