The DNA-binding specificity of the Bacillus anthracis AbrB protein.

The Bacillus subtilis AbrB protein is a DNA-binding global regulator of a plethora of functions that are expressed during the transition from exponential growth to stationary phase and under suboptimal growth conditions. AbrB orthologues have been identified in a variety of prokaryotic organisms, notably in all species of Bacillus, Clostridium and Listeria that have been examined. Based on amino acid sequence identity in the N-terminal domains of the orthologues from B.
