Catabolite repression is a biological process [1] that regulates gene expression in response to the availability of preferred carbon sources, such as glucose. When glucose is present, it inhibits the utilization of alternative carbon sources by suppressing the expression of genes involved in their metabolism [1]. This regulatory mechanism allows the organism to prioritize energy-efficient metabolic pathways [1]. Catabolite repression is observed in bacteria such as Escherichia coli and involves the cAMP-CRP complex as a key regulatory component [1].
