Catabolite Repression and Induction of Beta-galactosidase Synthesis in E. coli
Apart from induction, synthesis of β-galactosidase is also influenced by catabolite repression. The process involves slow down of the synthesis process, facilitated by lactose, especially when a presence of glucose is detected. Intuitively, glucose acts as a better energy and carbon source than lactose (Wallenfels, 1972, 67).
