title: Modulation of the two promoters of the galactose operon of Escherichia coli.
abstract: The gal operon of Escherichia coli is controlled by two independent promotors--one is activated and the other inhibited by cyclic AMP and cyclic AMP receptor protein. The two promotors are modulated, however, by the same operator locus and receptor protein.
