Difficulty: Intermediate
Description: This is the twentieth CASP10 Refinement Target. We've been told that ~77% of this model matches the native, so you'll need to refine ~23% of the structure! More info in the puzzle comments.

This is the page for this CASP10 refinement target:

The CASP10 organizers gave us this hint:

"Starting model GDT_TS=77."

GDT_TS=77 essentially means that 77% 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 84 & 176 are highly predicted to be part of a helix. However, the Valines at residues 64-65 & 99 are predicted to be part of a sheet.
