Ure2p of Candida albicans (Ure2albicans or CaUre2p) can be a prion in Saccharomyces cerevisiae, but the Ure2p of Candida glabrata (Ure2glabrata) cannot, even though the Ure2glabrata N-terminal domain is more similar to that of the S. cerevisiae Ure2p (Ure2cerevisiae) than is Ure2albicans. We show that the N-terminal N/Q-rich prion domain of Ure2 albicans forms amyloid that is infectious, transmitting [URE3alb] to S. cerevisiae cells expressing only the C. albicans Ure2p. Using solid-state NMR of selectively labeled C. albicans Ure2p1–90, we show that this infectious amyloid has an in-register parallel β-sheet structure, like that of the S. cerevisiae Ure2p prion domain and other S. cerevisiae prion amyloids. In contrast, the N/Q-rich N-terminal domain of Ure2glabrata does not readily form amyloid, and that formed on prolonged incubation is not infectious.
