Note(s): 1Several putative ArcA-binding sites with one or two mismatches are located within the betT promoter region.
1BetI is a repressor that regulates the betT promoter in response to the inducer choline.1BetI is a repressor that regulates the betT promoter in response to the inducer choline.
2Several putative ArcA-binding sites with one or two mismatches are located within the betT promoter region.
