title: [Gratuitous induction of beta-D-glucuronidase of Escherichia coli K 12].
abstract: The study of beta-D-glucuronidase induction with gratuitous conditions enabled us to strengthen the model of a dual negative regulation characterizing the biosynthesis of this enzyme. The concerted action of analogs structurally related to the natural inducers of the beta-D-glucuronidase demonstrates the cooperative effect of the two repressor molecules responsible for the blocking of the synthesis of the enzyme.
