Conformational Transitions in the Presence of Solvent and Internal Memory Effects — •Roland Netz, Julian Kappler, Jan Daldrop, Bartosz Kowalik, and Florian Brünig — Department of Physics, Free University Berlin, Arnimallee 14, 14195 Berlin, Germany

Conformational transitions of biological molecules are controlled by solvent friction. For fast transitions, such as dihedral-angle flips, the finite solvent memory time plays a role. General scaling laws for the transition time including inertial, friction and memory effects are presented. The interplay between fast molecular reconfigurations and long-time conformational relaxation and the coupling between solvent and internal friction effects is discussed.
