The Core existence bonus seems to be at least 470, not 420 max.
The residue count at start is 51, not 60 (with 275 bonus)
Is this an error in the puzzle or the description ?
Thanks for pointing this out! These are just problems with the description; the puzzle setup is okay.
I've corrected the max bonus for Core Existence. You're right that there are 51 designable residues. We had included the frozen loop residues when we figured the residue count of 60.
This puzzle has essentially the same structure as described in the notes for 1659b, only smaller, down to 307 segments from 499.
Once again, the puzzle has three protein chains, plus three ligands.
The ligands are the single-atom kind, represented as black dots. They're a little hard to see with dark background. Switching to a light background makes them easy to spot. As bkoep explained, the ligands are manganese atoms, and it's possible they could interact with the protein.
As previously, the first chain of the protein is "integrin alpha-V", but a trimmed-down version with only 116 segments instead of 193. It still matches 6DJP and other structures in the PDB.
The B chain is likewise "integrin beta-3", but only 128 segments instead of the 243 in 1659b. Again, you'll find a partial match in a 6AVU and others in the PDB. (You may notice that 6AVU also contains the A chain.)
The third chain, the C chain, is the designable part, and has the same starting sequence found in 1659b.
This time, we're down to only two disulfide bridges:
29,42 158,165
As before, you probably won't be able to do anything but break them, so probably best to leave them alone.
The recipe AA Edit 2.0 shows each chain and each ligand separately, making it easier to find the matching PDB entries.
It is suggested that this will be faster - it is not.
Reaction time to operations is dire.....Tho it is fair to say that crashes are less here (so far)
Truth is - this is not easily playable....I have spent some time trying....doubt I'll bother wasting much more on it tho.
I wish good luck to those with big machines.
As usual - these types of puzzles destroy the game part of this place - since only those with big machines can compete.
Sad but true.
Perhaps we can have this reposted smaller? less than 200 segs is a start. I appreciate that this puzzle is smaller in seg number than the last - but now there is an additional filter - so we're about where we were.
I (and many) want to work on this - any chance of enabling us to do so - sensibly?
It looks like Bruno Kestemont had the top-scoring solution, but it failed to register here on the Foldit site.
Residue IE Score (max +500)
Monitors that all PHE, TYR, and TRP residues are scoring well.
Core Existence (max
+420+470)Ensures that at least 25% of residues are buried in the core of the designed binder.
Residue Count (max +275)
Penalizes extra residues inserted beyond the starting 60, at a cost of 55 points per residue. Players may use up to 65 residues in total.
