Stereo-view of the active site overlay of Ms IspF and Ec IspF. Residues from Ms IspF are labeled and CDP-B is the depicted conformer. Protein atoms are colored: C of Ms IspF green, C of Ec IspF wheat, all N atoms blue, O atoms red, and Se atoms magenta. The marine sphere depicts the water molecule that contributes to solvent-mediated interactions between IspF and the ribose hydroxyls of CDP.
