abstract = {High resolution structural information on amyloid fibrils
is crucial for the understanding of their formation
mechanisms and for the rational design of amyloid inhibitors
in the context of protein misfolding diseases. The
Src-homology 3 domain of phosphatidyl-inositol-3-kinase
(PI3K-SH3) is a model amyloid system that plays a pivotal
role in our basic understanding of protein misfolding and
aggregation. Here, we present the atomic model of the
PI3K-SH3 amyloid fibril with a resolution determined to
3.4 Å by cryo-electron microscopy (cryo-EM). The fibril
is composed of two intertwined protofilaments that create an
interface spanning 13 residues from each monomer. The model
comprises residues 1–77 out of 86 amino acids in total,
with the missing residues located in the highly flexible
C-terminus. The fibril structure allows us to rationalise
the effects of chemically conservative point mutations as
well as of the previously reported sequence perturbations on
PI3K-SH3 fibril formation and growth.},
