RPSBLAST alignment for GI: 254780717 and conserved domain: cd01019

>gnl|CDD|29738 cd01019, ZnuA, Zinc binding protein ZnuA. These proteins have been shown to function as initial receptors in the ABC uptake of Zn2+. They belong to the TroA superfamily of periplasmic metal binding proteins that share a distinct fold and ligand binding mechanism. They are comprised of two globular subdomains connected by a single helix and bind their specific ligands in the cleft between these domains. 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 = 286
 Score =  223 bits (570), Expect = 4e-59
 Identities = 99/281 (35%), Positives = 142/281 (50%), Gaps = 19/281 (6%)
