Figure 2.
FIGURE 2. The iron-binding environment in FutA1. The top
stereo figure shows the electron density of iron bound to FutA1
and some of the contact residues, and the bottom stereo figure
shows some of the secondary shell contacts with the ligating
residues. The orientation here is similar to that in Fig. 1 with
the N-terminal domain toward the bottom of the figure and
looking into the iron binding pocket.
