If you are new to Foldit, make sure you have completed Intro Puzzles 7-1 through 7-4 before trying this puzzle.
This puzzle has the ResidueIE filter on (to ensure PHE, TYR, and TRP residues are scoring properly) and we've increased the Ligand Score by a factor of 10 to promote interactions with the sugar.
Tip: To see the parts of the sugar that you can bond to, check Show bonds (non-protein) and Show bondable atoms in the View menu. Make sure Show bonds (loop) and Show bonds (sidechain) are also on. Blue can bond to red, and purple can bond to either blue or red.
Crash Warning: Do not enable the 'Show Isosurface' view option, as it will crash with this puzzle. We hope to fix this soon!
Please note that the cuts on this puzzle cannot be closed!
They are just there to hold the region you are able to work on in place, without moving the rest of the frozen protein when you wiggle.
I have not been able to run any script doing mutate, I get:
string [[...}356: bagd argument #1 to GetAminoAcid (invalid argument)
We are looking into this problem:
For now, since the ligand is not mutatable, if you can exclude it from your mutate scripts that hopefully might help a bit.
In most of them in the beginning of the file segCnt (or segCnt2 in my DRW) is set.
Just add -1 to that line.
Example V2 recipe: segCnt=structure.GetCount() change that into segCnt=structure.GetCount()-1
And I still believe the filter doesn't work properly. It still penalizes Tryps etc although they are placed properly. It is a bit disappointing that I didn't receive feedback anymore after i posted it on 680
All of the carbons are marked as Acceptor/Donor, but some are missing polar hydrogens, and Foldit refuses to bond acceptors to them.
