'Digging up' 4-billion-year-old fossil protein structures to reveal how they evolved
Granada, Spain (SPX) Aug 09, 2013
Modern proteins exhibit an impressive degree of structural diversity, which has been well characterized, but very little is known about how and when over the course of evolution 3D protein structures arose. In a study published by Cell Press in Structure, researchers resurrected 4-billion-year-old Precambrian proteins in the laboratory and gained novel insights into protein evolution by analyzing their X-ray crystal structures. This method has revealed a remarkable degree of structural similarity ... read more
