News From the Field
Researchers Work to Untangle Knots, Slipknots in Species Separated by a Billion Years of Evolution

June 11, 2012

molecular structures of a protein Strings of all kinds, when jostled, wind up in knots. It turns out that happens even when the strings are long strands of molecules that make up proteins. A new study by scientists at Rice University and elsewhere examines structures of proteins that not only twist and turn themselves into knots, but also form slipknots that, if anybody could actually see them, might look like shoelaces for cells.
