title: Regulatory sites of cationic nature on skeletal myosin.
abstract: The kinetics of the Ca2+-ATPase of chicken skeletal myosin has been found to be of a biphasic type. DNP and SCN- increased Ca2+-ATPase activity, whereas CN- and HCO3- acted as inhibitors in the concentration range used. Upon raising substrate concentration, activation and inhibition constants for those modifiers responded also with an elevation of their values.
