Term Name: | carbon catabolite repression of transcription by glucose |
---|---|
Synonyms: | down regulation of transcription by glucose, down-regulation of transcription by glucose, downregulation of transcription by glucose, glucose effect, glucose repression, inhibition of transcription by glucose |
Definition: | A transcription regulation process in which the presence of glucose leads to a decrease in the frequency, rate, or extent of transcription of specific genes involved in the metabolism of other carbon sources. Carbon catabolite repression is a mechanism of genetic regulation which the accumulation of catabolites of one substance in the cell represses the formation of enzymes that contribute to the catabolism of other substances. |
