Abstract Transition metals, such as iron and zinc, are indispensable trace elements for eukaryotic life, acting co-factors in essential processes ranging from respiration metabolism to DNA replication. These metals can be transported into cells by an evolutionary-conserved family of metal transporters; however, how the ubiquitous mammalian parasite Toxoplasma gondii acquired has been unknown. Here, we have identified characterised first zinc importer T. . This transporter, named ZFT, localised plasma membrane is parasite’s life cycle. We find ZFT regulated availability overexpression sensitises excess zinc. Using a conditional knockdown system, that leads reduction mitochondrial switch more quiescent lifecycle stage. To confirm transport activity, parasite-associated iron, complements loss transporter activity yeast model. Overall, uptake demonstrated importance cell. finding reveals critical piece puzzle understanding this obligate intracellular thrives within its host.
