by kinetic analyses of assembly in the presence of the su45-actin complex and dilution-induced disassembly of filaments precapped with complex , we have estimated both the association rate constant ( 4.0 x 10 ( 4 ) m-1s-1 ) and the dissociation rate constant ( 0.05s-1 ) for the nonpreferred ends of actin filaments .
