Motivating !

"In rare cases, genetic mutations may alter both key amino acids at the same time, preserving their interaction so that the protein can continue to do its job. Evolution would favor such tandem mutations, which would cause the amino acid partners to coevolve."

"The trick to finding these coevolving pairs (...) was to look at the gene sequence of a protein from not just a single organism, but many".

And it worked !

"Baker’s group (...) was able to track enough coevolving amino acids to pin down the structures of 614 proteins, each one representing an entire family of proteins for which no structures exist".

Hopefully this kind of info would be build in our Foldit tools (Remix? Contact maps? I don't realize).

Contact maps

As far as I know, the contact maps in the recent contact map puzzles are generated from this coevolution data.
