Figure 1.
Fig. 1. Crystal structure of the AR·Adx complex.
AR-Adx contacts occur at the primary and secondary interaction
regions and the region between the [2Fe-2S] cluster of Adx and
the isoalloxazine ring of the FAD of AR. C-terminal residues of
Adx are also in contact with AR. The side chains of some
residues involved in polar AR-Adx interactions are displayed.
For close-ups of the contact sites see Figs. 3 and 4. The brown
triangle marks the position of Adx Lys66 and the green marks AR
Glu4, both residues maintaining another cross-link reported
recently (11, 12). Figure was produced with MOLSCRIPT (17).
