RPSBLAST alignment for GI: 254780717 and conserved domain: cd01020

>gnl|CDD|29739 cd01020, TroA_b, Metal binding protein TroA_b. These proteins are predicted to function as initial receptors in ABC transport of metal ions. They belong to the TroA superfamily of helical backbone metal receptor 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 = 264
 Score = 71.5 bits (175), Expect = 3e-13
 Identities = 45/239 (18%), Positives = 88/239 (36%), Gaps = 20/239 (8%)
