Abstract
We discuss the coupling of bending and torsional degrees of freedom fo r actin filaments. When a filament is placed in a situation of low sym metry, such as in contact with a surface, actin is shown to develop a spontaneous, non-zero curvature. We discuss the implications of this r esult on the interpretation of recent experiments which measure the bi nding modulus of biological filaments.
