Description: Fold a kinesin protein into an electron density map! This is a follow-up to Puzzle 1767, now starting with the crystallographer's structure! Players may also load in their solutions from Puzzle 1767. Note that this puzzle will only be up for 5 days, and will expire on December 13.

This is a monomer unit of the crystal structure 6IGN, which represents the coiled-coil stalk portion of a kinesin protein. Kinesins are motor proteins that transport cargo within the cell, by "walking" along the cellular cytoskeleton. This particular crystal structure has a poor R-free value, meaning that some of the x-ray diffraction data is poorly explained by the crystallographer's structure. We are curious whether Foldit players can build a better structure into the electron density map!
