By using analytical ultracentrifugation interactions of the small heat shock protein hsp25 and G-actin have been analyzed. Association constants of about 107 reciprocal molar concentration were estimated from the concentration distribution using a computer program based on the nonlinear least-squares methode. In the presence of an excess of actin up to four molecules of this protein were bound to hsp25 particles.
