Abstract Natural actomyosin was extracted from the thoracic flight muscle of newly emerged, mature, middle-aged, and senescent male house flies. The age-related change in the ATP-sensitivity of the actomyosin parallels the age-related distribution of the specific activity of the actomyosin ATPase, being significantly lower in the actomyosin of newly emerged and senescent male house flies than in the actomyosin extracted from mature organisms. These results indicate that the isolated flight muscle protein is, indeed, different for various ages of the house fly, most likely consisting of different ratios of the individual components of actomyosin.
