Fig. 8From: The LacI family protein GlyR3 co-regulates the celC operon and manB in Clostridium thermocellum Model of GlyR3 regulation. Expanded model of celC regulon. a In the absence of laminaribiose, GlyR3 auto suppresses the expression of the celC operon, resulting in relatively low GlyR3 concentrations, thereby allowing expression of manB. b In the presence of laminaribiose, repression of the celC operon is relieved resulting in high GlyR3 concentrations and repression of manB Back to article page
