A family of cytosolic copper (Cu) storage proteins (the Csps) are widespread in bacteria. The Csps can bind large quantities of Cu(I) via their Cys-lined four-helix bundles, and the majority are cytosolic (Csp3s). This is inconsistent with the current dogma that bacteria, unlike eukaryotes, have evolved not to maintain intracellular pools of Cu due to its potential toxicity. Sporulation inBacillus subtilishas been used to investigate if a Csp3 can store Cu(I) in the cytosol for a target enzyme. The activity of the Cu-requiring endospore multi-Cu oxidaseBsCotA (a laccase) increases under Cu-replete conditions in wild typeB. subtilis, but not in the strain lackingBsCsp3. Cuprous ions readily transfer fromBsCsp3, but not from the cytosolic copper metallochaperoneBsCopZ, toBsCotAin vitroproducing active enzyme. BothBsCsp3 andBsCotA are upregulated during late sporulation. The hypothesis we propose is thatBsCsp3 acquires and stores Cu(I) in the cytosol forBsCotA.
