Vacuoles isolated from pea (Pisum sativum), and wheat (Triticum aestivum) leaf protoplasts contained considerable activities of electrophoretically highly mobile exoamylases. Vacuoles from spinach (Spinacia oleracea) leaf and photoautotrophic Chenopodium rubrum suspension culture cell protoplasts were devoid of amylolytic activity. Endoamylase activity was in all cases associated primarily with the chloroplast.
