Abstract
We measured both the ATPase activity of actomyosin complex and the sli ding velocity of actin filaments on myosin heads under hydrophobic con ditions in the presence of ethanol. Both the ATPase activity and the s liding velocity decrease with the increase of ethanol concentration, i f the ionic strength is not too high. As ionic strength increases, the re appears an optimum concentration of ethanol that can enhance both t he ATPase activity and the sliding velocity.
