Term Name:	carbon catabolite repression of transcription
Synonyms:	carbon catabolite repression, negative regulation of transcription by carbon catabolites
Definition:	A transcription regulation process in which the presence of one carbon source 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.
