Abstract The metal-binding proteins of the body mass of the tropical rock oysterSaccostrea cuccullata from the iron-ore shipping terminals near Dampier, Western Australia, have been separated by gel chromatography and analyzed for Zn, Fe, and Cu. Appreciable amounts of Zn (40%) and Cu (25%) were eluted in association with a high molecular weight fraction (〉60,000 daltons), the major component of which was identified as the heat stable Fe-binding protein, ferritin (approx. mol. wt. 550,000), which also contains 95% of the Fe detected. Ferritin thus accounts for significant amounts of protein-bound Zn in this species and most probably in other bivalves containing elevated tissue levels of Zn.
