Definitions of H Meromyosin
Parts of the myosin molecule resulting from cleavage by proteolytic enzymes ( PAPAIN, TRYPSIN, or CHYMOTRYPSIN) at well- localized regions. Study of these isolated fragments helps to delineate the functional roles of different parts of myosin. Two of the most common subfragments are myosin S- 1 and myosin S- 2. S- 1 contains the heads of the heavy chains plus the light chains and S- 2 contains part of the double- stranded, alpha- helical, heavy chain tail ( myosin rod).
