The MgtE family of Mg(2+) transporters is ubiquitously distributed in all phylogenetic domains. Recent crystal structures of the full-length MgtE and of its cytosolic domain in the presence and absence of Mg(2+) suggested a Mg(2+)-homeostasis mechanism, in which the MgtE cytosolic domain acts as a 'Mg(2+) sensor' to regulate the gating of the ion-conducting pore in response to the intracellular Mg(2+) concentration ...
