High myosin atpase activity
WebMyosin ATPase activity can be determined at various salt concentrations (high and low salt concentrations), which uncover important information about the proteins. Myofibrillar ATPase activity at high salt concentration eliminates effects of actin and other proteins, and is sensitive to post-translational changes in myosin. WebJul 11, 2024 · During the actin–myosin cross-bridge cycle, myosin interconverts between an actin-activated state (with rapid ATP hydrolysis) and a disordered-relaxed state (DRX; with slower ATP hydrolysis)....
