Features of high- and low-resolution electron-density maps. (a) A section of the high-resolution structure of XRCC4 solved at 2.3 Å resolution. (b) The equivalent section to (a) from the low-resolution structure of Lif1 solved at 3.9 Å resolution. Note the loss of side-chain and main-chain features. (c) A section of β-sheet from the 3.9 Å resolution structure of Lig4. The region of β-sheet is shown as black sticks, while the remaining trace is depicted as black lines. In all three the maps are calculated with 2Fo − Fc coefficients and thus may have some model bias. |
