Which part of myosin filament has active sites for actin ??

Dear Student, Thick filament consist mainly of myosin protein. Myosin is split by enzyme trypsin in two fragments, called light meromyosin and heavy myosin. Heavy meromyosin consists of two globular subfragments and one rod shaped fibrous sub fragments. Each globular subfragment contains an ATP binding site and actin binding site. Thank You!
