Figure 7
Adaptive torsion restraints with an angle range of 120° applied to an arginine residue as displayed in the ISOLDE environment. Satisfied restraints (marked with a triangle) are coloured cyan; the colour shades through orange to red for unsatisfied restraints that are within the restraint well (marked `*'); restraints for which the current torsion is outside the well (marked `!') are coloured purple. The angle between the two `posts' indicates the current deviation between the torsion and the restraint target. The cyan wireframe and transparent surface are user-adjusted contours for a standard and sharpened crystallographic 2mFo − DFc map, respectively. The red wireframe is the −3σ contour of the mFo − DFc difference map (no positive difference density is visible in this view). |
