CC -!- FUNCTION: Mediates a low-level metal ion resistance, probably by efflux
CC of cations from the cytoplasm into the periplasm. Also mediates
CC resistance to cobalt, cadmium and zinc via regulation of the Czc
CC system. May repress expression of the Czc system by an export of the
CC inducing cations. Binds and transports zinc. Can also bind cobalt,
CC copper and nickel. {ECO:0000269|PubMed:10559151,
CC ECO:0000269|PubMed:15516561}.
CC -!- ACTIVITY REGULATION: Efflux is inhibited by FCCP.
CC {ECO:0000269|PubMed:15516561}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000269|PubMed:10559151}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:10559151}.
CC -!- INDUCTION: Most highly expressed when the upstream czcCBA transcript is
CC not induced. {ECO:0000269|PubMed:9044283}.
CC -!- DISRUPTION PHENOTYPE: Mutant is impaired in metal sensing. Deletion
CC leads to partially constitutive expression of the Czc system due to an
CC increased transcription of the czcCBA genes.
CC {ECO:0000269|PubMed:10559151}.
CC -!- SIMILARITY: Belongs to the cation diffusion facilitator (CDF)
CC transporter (TC 2.A.4) family. SLC30A subfamily. {ECO:0000305}.
