RPSBLAST alignment for GI: 254780717 and conserved domain: cd01016
>gnl|CDD|29735 cd01016, TroA, Metal binding protein TroA. These proteins have been shown to function as initial receptors in ABC transport of Zn2+ and possibly Fe3+ in many eubacterial species. The TroA proteins belong to the TroA superfamily of periplasmic metal binding proteins that share a distinct fold and ligand binding mechanism. A typical TroA protein is comprised of two globular subdomains connected by a single helix and can bind the metal ion in the cleft between these domains. In addition, these proteins sometimes have a low complexity region containing a metal-binding histidine-rich motif (repetitive HDH sequence).. Length = 276
