1 We find that the forward rate constant of the initial ATP hydrolysis (initial Pi burst) is about 5 times faster than the maximum turnover rate of the actin S-1 ATPase. Adenosine Triphosphate proteasome 26S subunit, non-ATPase 1 Homo sapiens
2 We, therefore, conclude that S-1 does not have to dissociate from actin each time an ATP molecule is hydrolyzed. Adenosine Triphosphate proteasome 26S subunit, non-ATPase 1 Homo sapiens
