Oxylate in the opposite direction. Because of their affinity for protons, binding sites for hydroxylate and NH3 might be similar. In either case, ammonium uptake would be active and driven by the chemical potential difference for NH3 and the electrochemical potential difference for protons (277, 300). A systems biology approach has been used to suggest that AmtB-mediated ammonium transport must be

Been confirmed by X-ray diffraction analyses of the complex (236, 237). Bending may increase the rate of transcription in vivo, as was suggested by the observed higher in vitro transcription rate using synthetic DNA-bending sequences at the E. coli lac promoter (238). This can then either activate or repress transcription. Activation or repression occurs if Crp-cAMP is correctly positioned with re
