Figure 2.

Overall structure of S. cerevisiae Tpa1 and electron density of the bound Fe(III) and 2OG. (A) 2Fo − Fc electron density map of Fe(III)–2OG and Fe(III)-coordinating residues in the ternary complex of S. cerevisiae Tpa1 (contoured at 1.5 σ). All the figures except Figure 1 were prepared using PyMol (DeLano, W. L., 2002, The PyMol Molecular Graphics System. DeLano Scientific, Palo Alto, CA, USA). (B) Topology diagram of Tpa1. α-Helices are shown as circles and β-strands as triangles. DSBH folds of NTD and CTD of S. cerevisiae Tpa1 are enclosed in gray boxes. (C) Stereo ribbon diagram of the S. cerevisiae Tpa1. α-Helices, β-strands and loops are colored in yellow, cyan and gray, respectively. Iron and 2OG bound near the center of Tpa1 NTD are shown in a sphere and sticks, respectively.
