LITERATURE
the todST operon is transcribed from a main promoter and that the +1 initiation point is located 31 nucleotides upstream from the A of the first ATG codon and is preceded by a -10/-35 canonical promoter. Expression from PtodS is under catabolite control, and in cells growing with glucose, the level of expression from this promoter is reduced, which in turn translates to low levels of the TodS/TodT regulators and results in a decrease of transcription from the PtodX promoter. The main underlying regulatory mechanisms of the tod structural genes are at the levels of catabolite repression control from PtodS and transcription activation, mediated by the TodT response regulator through a regulatory cascade in which the effector enhances autophosphorylation of TodS by ATP, with subsequent transphosphorylation of TodT
