CRYSTAL STRUCTURE OF A DIVALENT METAL ION TRANSPORTER CORA AT 2.9 A RESOLUTION.
Overview
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.
