説明
Actomyosins were prepared from the dorsal muscles of various fish species living in the frigid water zone and their biochemical activities were investigated.<br> 1) The specific Ca2+-ATpase activity of these actomyosins was generally lower than that of fishes living in the temperate water zone.<br> 2) The frigid water fish actomyosins exhibited a slightly lower ATP sensitivity than that of the temperater water fish actomyosin. Thermal inactivation of the Ca2+-ATPase activity of the former actomyosins was exactly of the first order reaction. These results suggest the presence of some actomyosin aggregates in the present actomyosin preparations.<br> 3) It was found by comparison of the inactivation rate constants of Ca2+-ATPase at 30°C that the actomyosins from Salmonidae and Osmeridae are 3-8 and 6-9 times, respectively, more unstable than that of carp. The actomyosins from some deep sea fishes of the North Pacific Ocean were more than 18 times less stable compared to that of carp.<br> 4) No clear relationship was found to exist between the inactivation rate constants of the actomvosins and their biochemical activities, such as specific Ca2+-ATPase activity and ATP-sensitivity.
