Sub-ångstrom cryo-EM structure of a prion protofibril reveals a polar clasp

The atomic structure of the infectious, protease-resistant, β-sheet-rich and fibrillar mammalian prion remains unknown. Through the cryo-EM method, MicroED, we reveal the sub-1Å resolution structure of a protofibril formed by a wild-type segment from the β2-α2 loop of the bank vole prion protein. Th...

description The atomic structure of the infectious, protease-resistant, β-sheet-rich and fibrillar mammalian prion remains unknown. Through the cryo-EM method, MicroED, we reveal the sub-1Å resolution structure of a protofibril formed by a wild-type segment from the β2-α2 loop of the bank vole prion protein. The structure of this protofibril reveals a stabilizing network of hydrogen bonds that link polar zippers within a sheet, producing motifs we name ‘polar clasps’.
