Researchers uncover novel process for creation of fuel and chemical compounds
Date:8/5/2014

tions according to the instructions specified by the cell's DNA. But without known or obvious activity, the products derived from these blueprints remained a mystery.

As time has gone on, however, researchers have realized that significant pieces of these genetic blueprints are directing the production of enzymes proteins that allow cells to build or take apart molecules in order to survive. These enzymes, it turned out, create new and useful compounds for society.

"I see this work as a prime example of the power of genomics," Donohue says. "It is not often that one identifies genes for a new or previously unknown compound in cells. It is an added benefit that each of these compounds has several potential uses as chemicals, fuels or even cellular antioxidants."

A cross-disciplinary, collaborative effort between GLBRC chemists, biochemists and bacteriologists in departments at UW-Madison and Michigan State University yielded the chemical identity of the fatty acid compounds and identified the specific genes that direct their synthesis in bacteria.

"I don't think this discovery would have been possible," says Rachelle Lemke, the paper's lead author and a research specialist in Donohue's lab, "without the analytical and intellectual expertise of the members from this center."
