A ferritin-like molecule was purified from iron-loaded cells of Saccharomyces cerevisiae, but its iron content was very low and was not representative of the cellular iron content. A study of the intracellular distribution of iron has shown that the vacuoles are involved in the storage of iron in the yeast cell. Moreover, it seems that this vacuolar iron can be further utilised by the cells for iron-requiring processes such as mitochondriogenesis.
Raguzzi et al. (1988) studied this question.
