Low affinity DNA-binding promotes cooperative activation of natural transformation in Vibrio cholerae

Allison C. Hullinger, Virginia E. Callahan, Triana N. Dalia, Ankur B. Dalia

This study shows that low DNA-binding affinity of TfoS promotes its dependence on ChiS for activating PtfoR, which is necessary for optimal Vibrio cholerae fitness on chitin.
