Description

This puzzle is a followup to Puzzle 1152: Foldit vs. UMich Electron Density Challenge. We were impressed with many players' solutions, and our UMich collaborators have a shared a higher resolution dataset of the same protein. Foldit solutions were used to develop a higher quality electron density map from the new dataset, and we’d like to see if players can use it to further improve this model! Pay special attention to residues 20-32 and 51-64, which were unresolved in Puzzle 1152. Note that players will not be able to load in solutions from Puzzle 1152.

I would like to know something about the model we have been given. And I suspect i am not alone.
Can you tell us what the resolution is on the ED map?

I am also curious about the R factor. Is it below 30%? Below 25%? (I confess to being a nerd, and a once-upon-a-time crystallographer.) But i think the community could benefit from some notion of how good the model is, and where we are in the process.)

Thanks.

bkoep mentioned this in chat: "Ah, actually, the UMich students are not involved in this challenge. I forgot to mention that in the puzzle description. For this puzzle, we're more interested in how Foldit solutions compare to those of expert crystallographers."

The resolution of this dataset is 1.8 Å.

The R factor is below 30%, so the starting model is pretty close to the correct structure.
