... assayed by varying the concen- tration of Tm in the presence of constant concentration of F-actin and myosin S1. In this condition, Tm inh ibits the ATPase activity as its concentration increases ... E. The actomyosin S1 Mg 2+ ATPase was determined in the absence of troponin as a function of tropomyosin concentration, and in the presence of troponin and Ca 2+ concent...
