carbon catabolite activation of transcription from RNA polymerase II promoter regulation of transcription from RNA polymerase II promoter by a nonfermentable carbon source positive regulation of transcription from RNA polymerase II promoter by a nonfermentable carbon source GO:0061414 A transcription regulation process in which the presence of a nonfermentable carbon source leads to an increase of the frequency, rate, or extent of transcription, from an RNA polymerase II promoter, of specific genes involved in the metabolism of other carbon sources. dph 2012-01-23T11:31:27Z biological_process
