Panel A: Structure of the gold complex with C154-C159 of SmTGR (site 1); panel B: structure of the gold complex with C2520-C574 of SmTGR (site 2); panel C: gold binding site of human GR [7]; panel D: antimony binding site of TryR. Notice that while gold is two-coordinated, antimony is three- or four-coordinated [20].
