Torsion and anchoring of protein filaments
Prof. Pedro Tarazona
Departamento de Fisica Teórica de la Materia Condensada, UAM
This informal seminar presents a possible explanation for the polymorphism observed in FtsZ protein filaments anchored on mica. The competition between a spontaneous torsion of the filament an a preferential anchoring on the surface is modeled as a physical pendulum equation, with multiple solutions associated to the number of untwisted rounds.
