Structural families of metal transporters. Individual elements on the abbreviated periodic table are shaded red if the are specifically imported by a member of that particular family or blue if they are effluxed. Metal ions that are transported non-specifically are shaded pink for uptake or light blue for efflux. The four-letter designations for individual proteins that perform the indicated function are given; this list is not meant to be comprehensive but rather shows representative members that have been structurally and/or functionally characterized (see text for details). Ribbon representations of crystallographic structures of one member of each family summarizes salient structural features of each transporter. The structures shown are 1) Archaeoglobus fulgidus CopA monomer, a Cu(I)-selective P1B-type ATPase (2VOY);71 2) Archaeoglobus fulgidus MoO4−—ABC transporter with MoO4− in red (2ONK);408 3) E. coli Zn(II) transporting CDF proteins YiiP with zinc atoms shaded red (2QFI);68 4) There are no reported structures for an Nramp transporter; 5) Combined hypothetical structure of an RND complex.
