Prion and nonprion amyloids: a comparison inspired by the yeast Sup35 protein
{{output}}
Yeast prion determinants are related to polymerization of some proteins into amyloid-like fibers. The [PSI(+)] determinant reflects polymerization of the Sup35 protein. Fragmentation of prion polymers by the Hsp104 chaperone represents a key step of the prion ... ...
