abstract = {Self-propagating β-sheet–rich fibrillar protein
aggregates, amyloidfibers, are often associated with
cellular dysfunction and disease.Distinct amyloid
conformations dictate different physiological
consequences,such as cellular toxicity. However, the origin
of the diversityof amyloid conformation remains unknown.
Here, we suggest thataltered conformational equilibrium in
natively disordered monomericproteins leads to the
adaptation of alternate amyloid conformationsthat have
different phenotypic effects. We performed acomprehensive
high-resolution structural analysis of Sup35NM, anN-terminal
fragment of the Sup35 yeast prion protein, and foundthat
monomeric Sup35NM harbored latent local compact
structuresdespite its overall disordered conformation. When
the hidden localmicrostructures were relaxed by genetic
mutations or solvent conditions,Sup35NM adopted a strikingly
different amyloid conformation,which redirected
chaperone-mediated fiber fragmentation and modulatedprion
strain phenotypes. Thus, dynamic conformational
fluctuationsin natively disordered monomeric proteins
represent aposttranslational mechanism for diversification
of aggregate structuresand cellular phenotypes.},
