Figure 5 The buried Lys117 contributes to nucleotide
accommodation. A stereo diagram of the active site of monomer A
of structure DP (bold colors) superimposed on the active site of
structure 1ng1 (Mg-^2+-GDP Ffh NG; faded colors). Nucleotides
and surrounding residues are shown with hydrogen-bonding
interactions between two waters and Lys117 of monomer A of
structure DP drawn as green dotted lines and those between one
water and Lys117 of 1ng1 shown in faded magenta. A dioxane
molecule (labeled `DOX') in the active site of structure DP may
stabilize Lys117 in a single conformation.
