|Description:||This is a throwback puzzle to the early days of Foldit. This protein is found on the surface of bacteriophage fd, a virus that infects E. coli. It is responsible for penetrating the cell membrane of the host bacteria, allowing virus to enter the cell. This protein contains four cysteines that oxidize to form two disulfide bonds. We are revisiting old Foldit puzzles so we can see how useful the recent additions to the game have been.
