Metal binding to the C-terminal region of the copper-responsive repressor protein CopY is responsible for homodimerization and the regulation of the copper homeostasis pathway in Enterococcus hirae. Specific involvement of the 38 C-terminal residues of CopY in dimerization is indicated by zonal and frontal (large zone) size-exclusion chromatography studies. The studies demonstrate that the attachment of these CopY residues to the immunoglobulin-binding domain of streptococcal protein G (GB1) promotes dimerization of the monomeric protein. Although sensitivity of dimerization to removal of metal from the fusion protein is smaller than that found for CopY (as measured by ultracentrifugation studies), the demonstration that an unrelated protein (GB1) can be induced to dimerize by extending its sequence with the C-terminal portion of CopY confirms the involvement of this region in CopY homodimerization.
