Discovery may lead to safer drinking water, cheaper medicine

A discovery that may pave the way to helping reduce health hazards such as E. coli in water could also make chemicals and drugs such as insulin cheaper to produce and their production more environmentally friendly. By creating a three-dimensional model, biochemists discovered exactly how the AceK protein acts as a switch in some bacteria to bypass the energy-producing cycle that allows bacteria like E. coli and salmonella to go into a survival mode and adapt to low-nutrient environments, such as water.
