By quantitative sodium dodecyl sulfate-polyacrylamide gel electrophoresis, paramyosin:myosin heavy chain molecular ratios were calculated for three molluscan muscles:Aequipecten striated adductor, Mercenaria opaque adductor, and Mytilus anterior byssus retractor; and four arthropodan muscles:Limulus telson, Homarus slow claw. Balanus scutal depressor, and Lethocerus air tube retractor. These ratios correlate positively with both thick filament dimensions and maximum active tension development in these tissues. The role of paramyosin in these muscles is discussed with respect to the following characteristics: force development, "catch," and extreme reversible changes in length.
通过定量十二烷基硫酸钠-聚丙烯酰胺凝胶电泳,计算了三种软体动物肌肉(栉孔扇贝横纹闭壳肌、硬壳蛤不透明闭壳肌和贻贝前足丝牵缩肌)以及四种节肢动物肌肉(鲎尾节、龙虾慢爪肌、藤壶盾板下压肌和大田鳖气管牵缩肌)中副肌球蛋白与肌球蛋白重链的分子比率。这些比率与这些组织中的粗肌丝尺寸和最大主动张力发展呈正相关。针对以下特性讨论了副肌球蛋白在这些肌肉中的作用:力的产生、“抓握”以及长度的极端可逆变化。
