Abstract excerpt

The repression of the carAB operon encoding carbamoyl phosphate synthase leads to Lactobacillus plantarum FB331 growth inhibition in the presence of arginine. This phenotype was used in a positive screening to select spontaneous mutants deregulated in the arginine biosynthesis pathway. Fourteen mutants were genetically characterized for constitutive arginine production. Mutations were located either in one of the...
