We have studied the core structure of amyloid fibers of yeast prion protein Sup35. We developed procedures to prepare straight fibers of relatively uniform diameters from three kinds of fragments; N… (More)
The interaction of Hsp104 with yeast prion fibers made of Sup35NM, a prion-inducing domain of Sup35, was tested. When fluorescently labeled Hsp104 was added to the preformed fibers, individual fibers… (More)
Using the yeast prion as a model, we have developed a novel system to observe the growth of individual prion fibers directly. NM fragments, the prion-determining region of the yeast protein Sup35p,… (More)
