Description

The structure of this protein has already been solved and published, but close inspection suggests that there are some problems with the published solution. We'd like to see if Foldit players can use the same electron density data to reconstruct a better model. This one has a big protein chain and then two smaller protein chains as well. Also, it's pretty gigantic, so the Trim Tool is highly recommended.

This is the SecYEG translocon of Methanocaldococcus jannaschii. There are multiple PDB structures of this complex and I don't know which one this is.

Blasting A gives an exact match at 2YXQ, which has no unmodelled residues in-between. Good!

Oh, and don't worry too much about burials. A good chunk of this thing sits in a lipid membrane.
