Description: This is a repost of Puzzle 715. When this puzzle ran in May of this year, the structure of this protein was still unknown. Now the structure has been published, and we're making the puzzle available for the Black Belt Folding broadcast! This puzzle will remain up for longer than usual so that players can practice their newly acquired de-novo skills. Players will NOT be able to load in any previous solutions for these puzzles.

Here are the secondary structure predictions!

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 Valine at residue 109 is highly predicted to be part of a helix. However, the Valine at residue 139 is predicted to be in a sheet!

The above predictions are already on the starting model (based on the horizontal lines in the above figure).


If you are a new Foldit player, please make sure you have completed all these tutorials before trying this puzzle:
- lonely sheets,
- lock and lower,
- rebuild,
- structure and rebuild,
- control over clashing.

803 for Black Belt?


I am under the impression that only puzzle 802 is going to be used in the Black Belt demonstrations. Please confirm this with katfish and auntdeen.

Yep, you're absolutely right

Yep, you're absolutely right Boots. 802 will be used in the demonstrations, and 803 is a practice puzzle with which everyone can try out their newly acquired skills.
