Abstract
Adrenal medullary and retinal myosins formed bipolar filaments in vitro. These filaments showed features suggesting flexibility in the rod region of the myosin molecules composing such filaments; in certain cases the myosin heads spread away from the filament backbone, in others the backbone itself was twisted. In addition the bare central backbone showed transverse striations.
摘要
肾上腺髓质和视网膜肌球蛋白在体外形成双极细丝。这些细丝呈现出的特征表明，构成此类细丝的肌球蛋白分子的杆状区域具有柔韧性；在某些情况下，肌球蛋白头部从细丝主干散开，在其他情况下，主干本身发生扭曲。此外，裸露的中央主干呈现出横向条纹。
