New views of enzyme structures offer insights into metabolism of cholesterol, other lipids

With the aid of X-ray crystallography, researchers at the University of Michigan have revealed the structures of two closely related enzymes that play essential roles in the body's ability to metabolize excess lipids, including cholesterol. The findings are an important step toward understanding and being able to therapeutically target disorders and drug side effects that cause lipids, including cholesterol, to build up in the body--leading to heart and kidney failure and other problems.
