Zn(2+) efflux transporter which is involved in detoxification of zinc during infection. ATP + H2O + Zn(2+)(in) = ADP + H(+) + phosphate + Zn(2+)(out) Induced during infection of D.discoideum and by elevated levels of Zn(2+). Deletion of the gene leads to growth inhibition in the presence of elevated levels of Zn(2+), but not Mn(2+) or Cu(2+) (PubMed:33531393). Deletion mutant shows strongly attenuated intracellular growth during D.discoideum infection (PubMed:33531393). Increasing concentrations of Mn(2+) does not affect the growth of the wild-type strain, nor that of the deletion mutant, excluding that M.marinum CtpC is a manganese exporter as M.tuberculosis CtpC. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily.
