1826: Coronavirus Trimmed ORF8 Prediction

Difficulty: Novice
Description: This is a follow-up to Puzzle 1823, but players noticed that the first 15 amino acids are highly predicted to be a signal peptide, so we have trimmed those residues from this puzzle. This protein is encoded in the viral genome of SARS-CoV-2, but the protein's structure is still unknown. If we knew how this protein folds, we might be able to figure out its exact function. Refold this different starting model to find higher-scoring solutions, which will tell us how this protein is most likely to fold!

I have some issue with the scoreboard. Cant see the scores from other players. Only getting a text saying 'Getting player list...'

No scoreboard scores here, either.

I just filed a report on the

I just filed a report on the feedback page. Some others in the veteran chat have been having the same issue it seems.

Thank you for reporting this...

We'll try to figure out what is going on.
Thanks for your patience.

My only though...

Was that it might have something to do with however the puzzle was made. My thinking is that whatever caused the puzzle's description to get goofed up with ?s being randomly swapped in for spaces, might also have caused a hidden issue in the puzzle's name, too.
If that's the case, perhaps the server isn't able to properly recognize the title and can't generate the scoreboard?

It could be encoding error.

It could be encoding error. Some encodings has different character codes for space or new line (it would explain those ?s) and different characters too.

That was my exact thinking. I just had never personally encountered one where (seemingly) arbitrary spaces get replaced like that! lol
I've seen apostrophes, line-breaks, special characters (like accented or other language), but can't say I've seen spaces! :D

I'm admittedly curious what DID end up to be the cause, now that it's fixed! heh

Not quite fixed...

Client shows I've soared to #1 on 1826, but website shows Steven Pletsch is still in command.

Something is borken.

OK, I guess the ferrets were just busy....

Client scoreboard now seems to match the website.

Glad it's finally back!

Disulfide bonds

Is it possible that some of the cysteins make disulfide bonds and other not ?

It's always possible...

Unfortunately, we really don't have any additional information about this protein... so we can't be confident one way or another.

I would suggest trying different topologies with and without disulfide bonds.

Hi Deconstruct!

Hi there! If you're interested in learning more and getting higher scores, I would suggest joining our discord channel to chat with other players and maybe get some helpful pointers!
