ribonuclease from bovine seminal plasma ( rnase bs ) interacts with skeletal muscle actin in the following way : it binds to actin with an apparent binding constant of 9.2 x 10 ( 4 ) m-1 in 0.1 m kcl , induces the polymerization of actin below the critical concentration in depolymerization buffer , accelerates the salt-induced polymerization of actin even at a molar ratio of rnase to actin lower than 1/100 , and bundles f-actin filaments .
