Putting Protein Structure Determination on the Fast Track

Using DOE's supercomputing resources and automated small-angle X-ray scattering instrumentation at an experiment station linked to Berkeley Lab's Advanced Light Source, researchers in one month resolved the three-dimensional structures of 40 proteins from Pyrococcus furiosis-a hydrogen-producing microbe thriving in boiling temperatures. Pictured here is one of the protein structures. This work would have taken several years with traditional X-ray crystallography techniques. By analyzing the molecular structures of this heat-tolerant microbe, scientists are working to understand which protein characteristics enable an organism to withstand the very hot and acidic conditions associated with biofuel production and other industrial processes.
