Residues near the amino terminus of Rns are essential for positive autoregulation and DNA binding.

Journal of bacteriology - 1 Apr 2008

Basturea Georgeta N, Bodero Maria D, Moreno Mario E, Munson George P

Abstract excerpt

Most members of the AraC/XylS family contain a conserved carboxy-terminal DNA binding domain and a less conserved amino-terminal domain involved in binding small-molecule effectors and dimerization. However, there is no evidence that Rns, a regulator of enterotoxigenic Escherichia coli virulence...
