Description: This is a design puzzle similar to Puzzle 879—now with 74 residues—near the interface of a target glycoprotein from the Ebola virus. At the binding site of the Ebola protein, there is already a helix designed by scientists in the Baker Lab, but the helix will not fold up by itself! Build a scaffold around the starting design that will fold up properly and stabilize the binding helix! There are strong constraints to keep the binding helix in place, and you may not mutate residues at the interface. You may not add additional residues to the design, but you may delete residues from one end of the design and reinsert them at the other end. This puzzle includes a Residue IE Score filter and a Core Existence filter, and High Wiggle Power has been disabled. Remember to share your favorite designs using the Share with Scientist tool, even if those are not your best-scoring solutions!

Core exists filter

Core exists filter appears to be taking into account residues from the ebola protein. The highest I was able to get it to with my current design was -480.

is it just me or is this kind

is it just me or is this kind of slow and stiff

2 dumb questions

The 104 - 106 segments - do we need to keep away from them because there is actually something there?

Seg 1 - serine - is that going to be connected to something else so needs room to do that?

Score issues

1. The ebola part of the score is so negative that normal scoring and seeing how far pointswise you are on the scoring ladder is not possible as long as the total score is negative.
This should be corrected.
2. The filters should only work on the design part of the puzzle, not on the Ebola part. (would probably also speed up the puzzle).
3. As a consequence of 1 scripts that cant cope with negative scores or change behavior depending on the score don't work correctly.
(TIP for my DRW users: use More options and disable skip fuze and replace qstab)
