NOTE: The Cut Tool IS available for this symmetry puzzle, but only in the Developer Preview.
(If you want to try it out, please read "How do I try out the Foldit Developer Preview?" in the FAQ: http://fold.it/portal/info/faq )
Once the next update posts (early next week) the Cut Tool will be available in main.
This is the page for this CASP10 refinement target:
Note that the organizers gave us this hint:
"Starting model GDT_TS=58."
GDT_TS=58 essentially means that ONLY 58% of the model superimposes correctly onto the native structure:
Here is the sequence logo predicted by the SAM server:
H = helix
E = sheet
C = loop (or coil)
The taller the letter at each position, the higher the probability of that specific secondary structure for that amino acid.
For example, the Valines at residues 23, 55, 85, 94, 112 & 115 are highly predicted to be part of a helix. However, the Valine at residue 34 is not predicted to be anything.
These were some of the possible templates for T0722:
This doesn't mean that TR722 folds up as a coiled-coil, but it might be a topology worth exploring.
We will try to post another Foldit Puzzle for TR722 where we give you just the starting model as a monomer (in case that it how the native folds up). It will likely be a very short puzzle.
