Structural highlights
Function
ZNTA_ECOLI Confers resistance to zinc, cadmium and lead (PubMed:9405611, PubMed:9364914, PubMed:9830000, PubMed:10660539, PubMed:17326661). Couples the hydrolysis of ATP with the export of zinc, cadmium or lead, with highest activity when the metals are present as metal-thiolate complexes (PubMed:9405611, PubMed:10660539, PubMed:17326661). Can also bind nickel, copper, cobalt and mercury (PubMed:10660539, PubMed:17326661).[1] [2] [3] [4] [5]
