| + | The bacterial CopC family of proteins are periplasmic copper binding proteins that act in copper detoxification. These proteins contain Cu(I) and/or Cu(II) binding sites, with the family that binds Cu(II) only the most prevalent, based on sequence analyses. Here we present three crystal structures of the CopC protein from Pseudomonas fluorescens (Pf-CopC) that include the wild type protein bound to Cu(II) and two variant proteins, where Cu(II) coordinating ligands were mutated, in Cu-free states. We show that the Cu(II) atom in Pf-CopC is coordinated by two His residues, an Asp residue and the N-terminus of the protein (therefore a 3N+O site). This coordination structure is consistent with all structurally characterized proteins from the CopC family to date. Structural and sequence analyses of the CopC family allow a relationship between protein sequence and the Cu(II) binding affinity of these proteins to be proposed. | ||
