CRYSTAL STRUCTURE OF CU(I)CUSF
Overview
Methionine-rich motifs have an important role in copper trafficking, factors, including the CusF protein. Here we show that CusF uses a new, metal recognition site wherein Cu(I) is tetragonally displaced from a, Met2His ligand plane toward a conserved tryptophan. Spectroscopic studies, demonstrate that both thioether ligation and strong cation-pi interactions, with tryptophan stabilize metal binding. This novel active site chemistry, affords mechanisms for control of adventitious metal redox and, substitution chemistry.
