Comprehensive model is first to map protein folding at atomic level

Scientists at Harvard University have developed a computer model that can fully map and predict protein folding for some 10 microseconds — about as long as some proteins take to assume their biologically stable configuration, and at least a thousand times longer than previous methods.

“This appears to have achieved a holy grail: simulating and predicting protein folding from a linear amino acid sequence,” said Ray Kurzweil. “It is only for small proteins but it shows the feasibility and obviously will expand to larger proteins over time.”

The work could help researchers better understand the abnormal protein aggregation underlying some devastating diseases, as well as how natural proteins evolved and how proteins recognize correct biochemical partners within living cells.
