==Crystal structure of a divalent metal ion transporter CorA at 2.9 A resolution.==
-
CorA family members are ubiquitously distributed transporters of divalent, metal cations and are considered to be the primary Mg2+ transporter of, Bacteria and Archaea. We have determined a 2.9 angstrom resolution, structure of CorA from Thermotoga maritima that reveals a pentameric, cone-shaped protein. Two potential regulatory metal binding sites are, found in the N-terminal domain that bind both Mg2+ and Co2+. The structure, of CorA supports an efflux system involving dehydration and rehydration of, divalent metal ions potentially mediated by a ring of conserved aspartate, residues at the cytoplasmic entrance and a carbonyl funnel at the, periplasmic side of the pore.

CorA family members are ubiquitously distributed transporters of divalent metal cations and are considered to be the primary Mg2+ transporter of Bacteria and Archaea. We have determined a 2.9 angstrom resolution structure of CorA from Thermotoga maritima that reveals a pentameric cone-shaped protein. Two potential regulatory metal binding sites are found in the N-terminal domain that bind both Mg2+ and Co2+. The structure of CorA supports an efflux system involving dehydration and rehydration of divalent metal ions potentially mediated by a ring of conserved aspartate residues at the cytoplasmic entrance and a carbonyl funnel at the periplasmic side of the pore.
