Figure 4
(a) Comparison showing the different conformations of the acidic loop backbone (region 55–72): chain A (blue), chain E (magenta) and the similar chain J (green) from the present CK2β^1–178 structure and chain D from the holoenzyme structure (grey, PDB code 1jwh ; Chantalat et al., 1999

). (b) Part of the acidic loop backbone in chain J within the 2F_o − F_c electron-density map contoured at 1.0σ above the mean density. The salt bridge between Asp59 and Arg47 is indicated in black.
