New computer system studies proteins.

New computer system studies proteins

Combining the latest in computer systems and magneticresonance spectroscopy, scientists at Stanford University have devised a more "natural' approach to analyzing protein molecules. Older methods of studying proteins, most notably X-ray crystallography, often artificially change their structures. But the magnetic resonance method--which relies on measuring the distances between atoms, as well as tracking their movements--can analyze proteins suspended in solution.

The computer system, called PROTEAN, compiles data onindividual proteins and can follow structural changes that occur during protein function. Described in the December JOURNAL OF BIOCHEMISTRY, the system takes about 24 hours of computer time to study a single protein.
