| Title | Friction of F-actin knots. | | Author(s) | Kirchner HO, Neukirch S | | Institution | INM-Leibniz Institute for New Materials, Saarbrücken, Germany. | | Source | J Mech Behav Biomed Mater 2010 Jan; 3(1):121-3. | | Abstract | We use the existing data of force-extension experiments on F-actin molecules tied into knots to compute a value of 0.15 for the static friction coefficient for contact between different parts of the same molecule with itself. This estimate for protein-protein friction is relevant for the stabilization of the 273 known proteins with knots, one percent of the structures deposited in the Protein Data Bank. | | Language | eng | | Pub Type(s) | Journal Article
