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 7, 43, 68 and 89 is highly predicted to be part of a helix. However, the Valine at residue 100 is not predicted to be anything!
The above predictions are already on the starting model (based on the horizontal lines in the above figure).
Cutaway view hint:
If you hover your mouse over a segment and type shift-Q, the game will hide parts of the protein and cloud that are not in the same plane as that segment - it cuts down on how much cloud you see at one time and makes it easier to focus. Q returns to normal view.
New Electron Density Features:
- Notes can be added to the electron density if present. To add one, press TAB with the mouse over the density while the density panel is open. Use the recycle button in the note panel to erase one. (Note: saving and sharing these notes is a feature that should be in a future release)
There is a video on our YouTube channel explaining how to add Notes to the electron density
- There is a button in the Electron Density Panel to focus rotation on the density. You can use the HOME or Q keys to refocus on the protein.
- The density score of a residue may now be viewed in the tab menu
We are unable to let you load in your solutions from previous CASP ROLL R0034 Puzzles, because the sequence has been trimmed (due to the electron density) compared to the previous puzzles.
