binding curves of tropomyosin-troponin [ consisting of all three subunits ( holotroponin ) ] and of tropomyosin-troponin-t-i to actin filaments were analyzed by separating the affinity of tropomyosin-troponin for actin filaments and the affinity for the end-to-end contact of tropomyosin molecules .
