Myosin head groups
WebAug 8, 2024 · Less than 20% of the myosin molecules were in a folded-head state in the absence of mavacamten, and ∼60% were in a folded-head state in the presence of mavacamten (Fig. 3H). The discrepancy between the fraction of closed-state myosin heads in the EM study (∼60%) and the fraction of SRX in the ATP turnover experiments (100%) is … WebOne part of the myosin head attaches to the binding site on the actin, but the head has another binding site for ATP. ATP binding causes the myosin head to detach from the actin (Figure 4d). After this occurs, ATP is converted to ADP and P i by the intrinsic ATPase activity of myosin.
