Two different mechanisms mediate catabolite repression of the Bacillus subtilis levanase operon.

Journal of bacteriology - 1 Dec 1995

Abstract excerpt

There are two levels of control of the expression of the levanase operon in Bacillus subtilis: induction by fructose, which involves a positive regulator, LevR, and the fructose phosphotransferase system encoded by this operon (lev-PTS), and a global regulation, catabolite repression. The LevR activator interacts with its target, the upstream activating sequence (UAS), to stimulate the transcription of the E...
