Exploring the super-relaxed state of myosin in myofibrils from fast-twitch, slow-twitch, and cardiac muscle
Muscle myosin heads, in the absence of actin, have been shown to exist in two states, the relaxed (turnover ∼0.05 s(−1)) and super-relaxed states (SRX, 0.005 s(−1)) using a simple fluorescent ATP chase assay (Hooijman, P. et al (2011) Biophys. J.100, 1969–1976). Studies have normally used purified p...
