Metals/Ions Comment Organism Structure
Iron cytosolic and mitochondrial isoenzyme require an intact [4Fe-4S] cluster. Mitochondrial aconitase is isolated predominantly in the [3Fe-4S] form (Fe/S ratio of 0.73) and must be activated by the addition of Fe2+. The cytoplasmic aconitase as isolated is about 80% active with a Fe/S ratio of 1.1 Bos taurus
