Scientists present 'moving' theory behind bacterial decision-making
Date:11/24/2008

lso sheds light on the specific bacterial protein responsible for producing anthrax toxins.

One of the transition-state regulators studied by the NC State biochemists, called AbrB, helps control the production of the three toxins in anthrax: lethal factor, edema factor and protective antigen. Production of all three of these toxins is necessary to make anthrax lethal.

Cavanagh and Bobay say that knowledge of AbrB's function could make it a likely target for a drug that would knock out its function. That would prevent anthrax from "going lethal."

"We now know more about the protein that causes you to die from anthrax poisoning and a brand new way of understanding how important proteins bind to targets," Cavanagh said. "This presents a whole new paradigm for drug design in the arms race against harmful bacteria and disease."
