摘要	Amyloid peptide (AP) self-assembly is a hierarch-ical process. However, the mechanistic rule of guiding peptides toorganize well-ordered nanostructure in a clear and precise mannerremains poorly understood. Herein we explored the molecularinsight of AP motif aggregates underlying hierarchical process withhelicalfibrillar structure by atomic force microscope, cryo-electronmicroscopy (cryo-EM), and molecular dynamics simulation. APassembly encompasses well-ordered twistedfibrils with uniformmorphology, size, and periodicity. More importantly, a hetero-zipper beta-sheet was identified in a protofilament of AP assemblydetermined by cryo-EM with a high resolution of 3.5 A. Eachpeptide heterozipper was further composed of two antiparallel beta strands and arranged by an alternative manner in a protofilament.The hydrophobic core and hydrophilic area in each zipper played the significant role for peptide assembling. This work proposedand verified the rule facilitating the basic building unit to form twistedfibrils and gave the explanation of peptide hierarchicalassembling
