Description: Note: Due to a scoring issue, this puzzle has been moved to devprev, and will be worth zero points. Redesign the active site to bind aflatoxin! This is Round 11 of the Aflatoxin Challenge. Since the last round, the Siegel Lab has introduced a few mutations in the active site, which might allow for some new redesign. This time, we're asking players to focus on just one loop of the starting structure, which clashes with the aflatoxin ligand in the binding pocket. Players may insert up to 20 extra residues into the designable loop, at a cost of 20 points per residue. Parts of the scaffold protein have been trimmed to reduce the size of the puzzle, and we've upweighted ligand interactions by a factor of five. We'd like to see if Foldit players can design proteins that make more interactions with the ligand! See the blog for more details.

Aflatoxins are a class of poisonous compounds that contaminate a significant portion of the global food supply. In this puzzle, players are challenged to redesign an enzyme that could break down aflatoxin molecules. The majority of the protein is frozen, with the aflatoxin ligand fixed in a binding pocket. Surrounding the binding pocket are a number of loops that might be redesigned without affecting the folding stability of the protein. In these loops, players may manipulate the protein backbone and mutate the residue sidechains. Redesign the loops of this protein to better bind the aflatoxin ligand!

This is the eleventh puzzle of our Aflatoxin Challenge, sponsored by Mars Inc. and Thermo Fisher Scientific. Promising designs will be tested by the Siegel Lab at UC Davis. By participating in the challenge/game, the players agree that all player designs will be available permanently in the public domain, and the players will not seek intellectual property protection over the designs created as part of the challenge/game.

Scoring is not working correctly

We now have two players with score over one million, and when running the recipe Random Idealize it appears that the unfiltered score is posted to the leaderboard, not the one after the penalty for extra segments. This is distorting the scoring.

A score of 112.9 billion for GlenB..

Is a bit out of range. Please fix this puzzle :)

.

Those are some big numbers!

We're working on figuring out what's going on here.

Does anyone have some reliable steps to reproduce this?

Lol. My computer is dead now.

Lol. My computer is dead now. I think did bandfun and compress. I should have uploaded mine I was the first person to screw it up.

1000000+ scoring

Nothing so far wrong with scoring according to y very blind eyes. A glycine Hinge on seg 13 will cause the jump.

it APPEARS that segs 13-60 should be checked for locked status, possibly other non-active areas also.

procedure to recreate

A good hinges recipe will do it, see the feedback: https://fold.it/portal/node/2006116
