Description: Apoptin is a viral protein of special interest because it targets cancer cells and causes apoptosis. Solving this protein structure would greatly advance research into apoptin’s functionality and development as a method to treat cancer. Resetting the puzzle will cycle through 5 Zhang server predictions that are also in the Alignment Tool so you can use partial threading. So that you have plenty of time to try out each model, this puzzle will be up for 10 days and worth 150 global points! More info in the puzzle comments.

More info:

Here are the secondary structure predictions 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 Threonines at residues 41 and 43 are highly predicted to be part of a sheet. However, the Threonines at residues 68 and 114 are not predicted to be anything!

Great question!

Thanks for bringing this up, MikeCassidy!
(I'm glad to see that my last sentence in this blogpost worked so fast :-)

We did NOT turn on the Disulfide Count Score Filter on this puzzle, but it can easily be added if needed.

I have asked the scientists at the Worcester Polytechnic Institute who are working on this unsolved protein for their expertise on the matter.

Thank you again for asking this!
