Figure 1.
Fig. 1. The FIH-CAD complex (a-c, structure 1; d,
structure 2). a, FIH monomer. The CAD peptide is shown as a
ball-and-stick representation in red and the DSBH motif in
green. b, FIH dimer. The two molecules of FIH are in dark and
light blue, the DSBH motif is in green, and the CAD peptide is
in red. c, the 2OG binding site with bound NOG is shown in
yellow. The Fe^(II) is colored pink, and the 2mF[o]  DF[c]
electron density map is contoured at 1.5  . d,
orientation of CAD Asn803 at the FIH active site. The 2OG and
CAD peptide are shown in yellow.
