Figure 4
(a) B-factor values for the OE1 and OE2 atoms in Glu residues in proteinase K. (b) Experimental electrostatic potential density maps, (c) scaled theoretical electrostatic potential maps and (d) scaled theoretical electron-density maps for the Glu48 side chain with two hydrogen bonds marked with dashed lines. All density maps are shown at a 2.5σ contour. |
