WebThe periplasm is a key location for metal partitioning. Bacterial ATP binding cassette (ABC)-type importers include substrate binding proteins which may be free within the periplasm or anchored to the outer face of the plasma membrane. It is anticipated that these proteins assist in loading metal ions onto the correct importers. WebCopC is a periplasmic copper-binding protein (17) suggested to work in concert with CopD (15). Copper-inducible expression of these proteins is regulated by the CopRS two-component system.
