The dispersion of carotenoid droplets in permeabilized goldfish xanthophores is dependent on ATP, F-actin, and cytosol. We report here that the motor (ATPase, translocator) resides with the permeabilized cell remnants and not in the cytosol. We also report that the carotenoid droplets have an ATPase that is not conventional myosin, dynein, or an ion pump. Its activity appears to correlate with the actin content of the carotenoid droplet preparation. A carotenoid droplet protein of Mr 72,000 (p72) is shown to be labeled by irradiation with 8-azido-ATP with concomitant loss of ATPase activity of the carotenoid droplets. We propose that this protein may be the ATPase responsible for carotenoid droplet dispersion.
