NOTE: Numbering is off as the first 21 residues were trimmed, so this secondary structure prediction might help:
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.
Note that these secondary structure predictions are not necessarily present in the models that have been provided in the puzzle.
