the kinetics of the mg2+-dependent atpase ( adenosine triphosphatase ) activity of bovine cardiac myosin and its papain subfragment-1 were studied by using steady-state and pre-steady-state techniques , and results were compared with published values for the corresponding processes in the atpase mechanism of rabbit skeletal-muscle myosin subfragment-1 .
