RPSBLAST alignment for GI: 254780717 and conserved domain: cd01137

>gnl|CDD|29740 cd01137, PsaA, Metal binding protein PsaA. These proteins have been shown to function as initial receptors in ABC transport of Mn2+ and as surface adhesins in some eubacterial species. They 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 = 287
 Score =  120 bits (302), Expect = 5e-28
 Identities = 67/285 (23%), Positives = 122/285 (42%), Gaps = 19/285 (6%)
