[中文釋義] 酶解肌球蛋白亞群碎片
[英文釋義] 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).
