  • Title: Metabolite repression and inducer exclusion in the proline utilization gene cluster of Aspergillus nidulans.
    Author: Cubero B, Gómez D, Scazzocchio C.
    Journal: J Bacteriol; 2000 Jan; 182(1):233-5. PubMed ID: 10613888.
    Abstract:
    The clustered prnB, prnC, and prnD genes are repressed by the simultaneous presence of glucose and ammonium. A derepressed mutation inactivating a CreA-binding site acts in cis only on the permease gene (prnB) while derepression of prnD and prnC is largely the result of reversal of inducer exclusion.
