We want to optimize the geometry of protein: +* in proximity of zinc, with quantum mechanics, +* its neighbourhood with a lower level of theory quantum mechanics, +* and the rest of protein with Rosetta's energy field. + +

+
+ +Therefore, the protein will be seperated into three regions, which will be called reg1, reg2 and reg3, respectively. Then, different movers and scorings will be applied for each reigon. + +Residue selectors ae used to specify each region.`reg1` is selected by residue numbers, and `reg2` is selected by `Neighborhood` selector. This selector compares the distance between beta carbons of selection (in this case, `reg1`) with beta carbons of other residues. If the distance is less than or equal to the threshold (in this case, 4A) it selects that residue. The `include_focus_in_subset="false"` tag means `reg2` excludes `reg1`. Figure 2. highights `reg1` with dark blue, and `reg2` with light blue. `reg3` is selected as anything not in `reg1` or `reg2` regions. + +``` + + + + + +``` +
