1 While caldesmon inhibited heavy actomeromyosin ATPase activity, it greatly enhanced binding of both unphosphorylated and phosphorylated heavy meromyosin to actin in the presence of MgATP, reducing the Kd for binding by a factor of 40 for each form of heavy meromyosin. meromyosin actin epsilon 1 Bos taurus
