Description

This is our fifth electron density puzzle with real data. Unlike the previous puzzles, there are bits of density which don't belong to the copy of the protein that you're working on. However, the protein you're working on should fit entirely within the density box. You'll have to decide which bits of density to match with, and which bits to ignore. Try to fit the protein into the density to get the best score! Secondary Structure Predictions are posted in the puzzle comments.

[beta_helix]

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 amino acid Leucine at residue 80 is highly predicted to be part of a sheet. However, the Isoleucines at residues 12 & 44 have an equal probability of being anything.
