Description

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 first 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.



Note: Due to special interest in this puzzle, the deadline has been extended by one week, to October 31 at 23:00 UTC.

smortier, per your request…connection issues discussed in IRC. Loaded 1440 approx. 0100 PST. Beginning around 0200 until bed (0600), various rhythmic connection issues. Diagnostics said it was neither me nor Comcast, but Comcast is infamous for late Sunday night undocumented meddlings. "Signature" of such is usually the rhythm pattern. Aside from dropped connections (very unusual here), variety of upload/download problems on shares, continuing into today. Top share on 1440 crashing regardless of client I try it on…unusual problems, not the usual garden variety we're familiar with. Sorry for not being more specific, problem's being especially vague (all the usual diagnostics /corrections/workarounds done, to not much avail). Thanks…

The loops tend to go crazy if I move one fairly radically, then wiggle. They stretch their cutpoints out really long, then zip back and go beyond, causing intersections with other SS, and my score goes to like -400000. Have to run a recipe to slowly work out the stresses before I can work on the moved loop. Adding bands just aggravates the loops, makes them go wilder. Make progress slow.

I would like to know if the sponsoring parties also agree to not patent the designs or derivatives and place them in the public domain ?

A question on 1440, is it important to have as many bonds as possible on the ligrand? or just go for high score>

I would like to see a legally binding statement by the promotors (and affiliates) that they too will abide by the rule that all their findings and derivatives will be in the public domain.

I agree that another sentence or two wouldn't hurt, but the term "public domain" is reasonably clear, and it appears in the blog post and the puzzle description. I did miss it the first couple of times I looked, could be a late edit, but I think I got hung up on the part about players not seeking their own IP protection for results. The Foldit Terms and Conditions (dated 8 March 2013) never allowed that anyway, as far as I can tell, giving the University of Washington the right to decide who owns what, results-wise.

One handout we received before the aflatoxin launch mentioned all results being in the public domain. The blog post is basically the same text as the handout, but adds the part about players not agreeing not to seek IP protection.

I added a comment to the blog post asking for a bit more clarity on the IP issue.
