Figure 4.
Figure 4. A stereoview of the electron density around the xylulose 1,5-bisphosphate molecule. In (a), the 2 F[o] F[c] amplitudes are shown with contour level 1σ . The 1-phosphate is to the left and the C2 carbonyl is marked (476CO). In (b), the F[o] F[c] map shows electron density (5σ) for the hydrate bisphosphate. The gem-diol conformation has been superimposed (heavier lines) over the ketose form of the molecule. Figure 4. A stereoview of the electron density around the xylulose 1,5-bisphosphate molecule. In (a), the 2 [3]mid F[o] [4]mid − [5]mid F[c] [6]mid amplitudes are shown with contour level 1σ . The 1-phosphate is to the left and the C2 carbonyl is marked (476CO). In (b), the [7]mid F[o] [8]mid − [9]mid F[c] [10]mid map shows electron density (5σ) for the hydrate bisphosphate. The gem-diol conformation has been superimposed (heavier lines) over the ketose form of the molecule.
