From: Atomic structure of PI3-kinase SH3 amyloid fibrils by cryo-electron microscopy
Side view of the secondary structure of the atomic model. a Single subunit i highlighted in blue with adjacent subunits in beige, described by even numbers, while the subunits of the opposite protofilament are described by odd numbers. b View of the minimal fibril unit (i) to (i-6) in one filament. The minimal fibril unit is displayed from two views by a turn of 180° highlighting the course of one monomer spanning several fibril layers
