The location of polyphenol oxidase (PPO) in cells of apple fruit was examined by immunohistochemistry and subcellular fractionation. In mature apple fruits, where vacuoles occupy most of the cells, PPO was detected immunochemically near the cell walls with use of anti-apple PPO antibodies. In cells of immature fruits and tissue culture, PPO was detected in organelles other than the vacuoles, probably in plastids. The plastid fraction was purified by density gradient ultracentrifugation, and the activities of PPO and marker enzymes of plastids were the highest in the plastids. Most apple PPO was in plastids, as are other plant PPOs, and some of the protein was solubilized and proteolyzed during ripening and storage.
