the timecourse of atp hydrolysis consisted of an initial rapid phase followed by a steady-state hydrolysis rate of 0.4 s-1 , indicating that the rate-limiting step of the atpase in isometric fibers is slower and subsequent to the nucleotide hydrolysis step : the isometric steady state intermediate is probably an actomyosin-adp complex .
