This is only the second revisit to puzzle 786. Puzzle 845 was the first revisit: https://fold.it/puzzles/996898

The protein in this puzzle is 2MCT, protein ZP_02042476.1 from Ruminococcus gnavus. The PDB entry is from 2013, but it still shows "to be published".

AlphaFold had a go at this protein, great except for the first 22 residues sticking out into space, then the rest looks somewhat OK: https://alphafold.ebi.ac.uk/entry/A7B6R4

So maybe AlphaFold is not infallible?

[Serca]

The first 20 amino acids, which are not present in this puzzle but are present in the Alphafold solution, seem to constitute the signal peptide. That is, they are a part of the protein destined to be removed by intracellular organelles that help to fold it.

Thanks @Serca, I'll have to look at the AlphaFold solution in more detail. I'd assumed that AlphaFold was using the sequence from 2MCT.

Meanwhile, I put together a guide for this puzzle, making it more like the other revisits: https://foldit.fandom.com/wiki/Revisiting_puzzle/786:_De-novo_Freestyle_30
