WebThe head of the myosin molecule has a site which binds to a complementary site on actin and, about 3.5 nm away, an ATP binding site which has a high ATPase activity only when myosin is bound to actin. The affinity of the binding to actin is regulated by events at the ATP binding site. india friend or foeWebApr 1, 2012 · Myosins can be found in nearly any cellular location, where they are thought to link each cargo to the actin cytoskeleton for transport and/or anchoring. lmw cnc latheWebAs the head of the myosin filament lies next to the actin filament, it is able to bind each temporarily.
