1) On M-actomyosin preparation of squid muscle purified by reprecipitations, its responses of streaming birefringence (SB) and of viscosity to adenosinetriphosphate (ATP) added were studied togather with superprecipitation. 2) The changes of SB stood in harmony with those of viscosity, suggesting that dissociation and recombination of M-actomyosin occurred successively when ATP was added. Superprecipitation was also confirmatively found with M-actomyosin. 3) In the process of ATP-responses of SB and viscosity, the adenosinetriphosphatase (ATPase) activity of M-actomyosin was found to be inhibited by Mg ion. It was shown that, as far as the effect of alkali earth metals on ATPase activity is concerned, M-actomyosin of squid is not distinct from actomyosin of rabbit and carp.
