ATP binds to myosin,breaking the linkage between actin and myosin and thereby allowing the crossbridges to dissociate from aactin.
Phosphorylation of myosin drives the crossbridge away from the thick filament backbone.
Ca2+ binds to cacalmodulin , a Ca2+ binding protein that is present in the cytosol of most cells and whose structure is related to that of Troponin.
Cytosolic Ca2+ decreases as actively transport Ca2+ back into the sarcoplasmic reticulum.
Active myosin light chain kinase then uses ATP to phosphorylate myosin light chains in the globular head of myosin.
ATP bound to myosin is hydrolysed , energising the crossbridge and another round of crossbridge occur as long as Myosin light chain are phosphorylated.
Energised myosin crossbridge are then able to bind to actin.
Finally as cytosolic Ca2+ decreases, myosin light chain phosphatase dephosphorylates myosin, which is then unable to bind actin and muscle relaxation occurs.
Crossbridge binding triggers the release of ATP hydrolysis products from , which produces the power stroke.
To begin there must be rise in Ca2+ that enters the cytosol drom inside of the sarcoplasmic reticulum or from the extracellular fluid.
The activated calmodulin- Ca2+ Complex binds to another cytosolic protein, myosin light chain kinase thereby activating the enzyme.
