Description

We are giving you another currently unsolved protein as an extended chain, but this time only GUI scripts are allowed and sharing has been disabled. After this puzzle expires, the puzzle will be re-posted and LUA scripts and sharing will be allowed. You'll be able to load in your solutions from this puzzle and use scripting and sharing. The secondary structure predictions are provided on the starting model, with more details posted in the puzzle comments.

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 32 & 42 are highly predicted to be part of a sheet. However, the Valines at residues 9 & 10 are highly predicted to be in a helix!

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.

Because this is the first Hand-Folding puzzle starting from an extended chain (without templates) we are giving you an extra week to use all your Hand-folding skills!
