Note(s): 1CRP is required for exuR transcription in a sugar-independent manner, irrespective of whether the bacteria are grown with glucose or glucuronate as the main carbon source Tutukina MN,2016, and this might be due to its cAMP-independent binding to a nonspecific site leading to only a secondary effect Kolb A, Busby S, Buc H, Garges S, Adhya S,1993.3CRP is required for exuR transcription in a sugar-independent manner, irrespective of whether the bacteria are grown with glucose or glucuronate as the main carbon source Tutukina MN,2016, and this might be due to its cAMP-independent binding to a nonspecific site leading to only a secondary effect Kolb A, Busby S, Buc H, Garges S, Adhya S,1993.
