Knotoids and knotted proteins

Agnese Barbiensi (University of Oxford)

Monday 14th December, 2020 16:00-17:00 Online


A small percentage of catalogued proteins is known to be knotted. Understanding the biological meaning of the presence of knots in proteins is an open and challenging question in biology. Entanglement in proteins is sometimes studied using knotoids, a generalisation of knots, recently defined by Turaev. I will introduce knotoids (and a few results on them) and explain how they can help in classifying knottiness in proteins. This is based on joint work with D.Goundaroulis and on ongoing collaboration with researchers from Oxford. 

The talk will be preceded by a tea time at 3:45pm. The Zoom link for the seminar is and the passcode is the genus of the two-dimensional sphere (4 letters, all lowercase).
