Figure 4
The distances (labeled in Å) between C1/NAG4/A and OD2/ASP52 in the A and B conformations are shown as yellow dashed lines. The blue and olive contour lines represent 2Fo − Fc maps at 1.5σ and 0.6σ for the complex in D2O, respectively. Atoms are shown as sticks (green, carbon; red, oxygen; blue, nitrogen). |
