Improved technique determines structure in membrane proteins
Date:8/17/2008

just a few milligrams of protein.

The determination of protein structure benefits not only from improvements in technology, but also from the researchers' novel approach to refining geometrical parameters.

Structure determination is normally based upon distances between atoms. Rienstra discovered a way of measuring both the distance between atoms and their relative orientations with very high precision.

"Using this technique, we can more precisely define the fragments of the molecule, and how they are oriented," Rienstra said. "That allows us to define protein features and determine structure at the atomic scale."
