Protein
Copper chaperone CopZ
Organism
Archaeoglobus fulgidus (strain ATCC 49558 / VC-16 / DSM 4304 / JCM 9628 / NBRC 100126)
Function
Chaperone that serves for the intracellular sequestration and transport of Cu(+). Delivers Cu(+) directly to the transmembrane transport sites of copper-exporting P-type ATPase A (CopA). Probably has a redox function due to the presence of a 2Fe-2S cluster and could reduce Cu(2+) to Cu(+).
