Fig. 9.

IspE ligand interactions in complex I. In both sections of this figure atoms are coloured blue N, red O and orange P. The C atoms of protein are beige, of CDPME green and ADP yellow. Residues that interact with the ligands are labelled, water molecules have been omitted for the purpose of clarity and some of the potential hydrogen bonds are shown as black dashed lines. (A) Stereo-view of the CDPME-binding site. (B) Stereo-view of the ADP-binding site.
