Figure 1. Structure of the homodimer of EAL domain of FimX with bound 5′-pGpG.

(A) Structure of the homodimer of EAL domain of FimX with bound 5′-pGpG. The secondary structure elements are labelled on one monomer. (B) Stereo view of the superposition of homodimer of EAL domain of FimX in apo form crystallized in spacegroup P2₁2₁2₁ (dark blue and light blue) on the homodimer of FimX EAL in complex with 5′-pGpG crystallized in spacegroup P4₃2₁2 (red and green).
