      Recent studies have identified conformational variants of α-syn strains that exhibit distinct neurotoxicity, seeding abilities, and propagation, which contribute to different properties of α-synucleinopathies (24, 25). Given that α-syn PFF induces PARP activation and PAR accumulation, PAR then accelerates α-syn fibrillization and changes Cited by: Klingstedt, T. & Nilsson, K. P.

Abstract. Poly 8-bromoadenylic acid [poly(BBrA)] is the only known all-syn polynucleotide. It shows a helix-coil transition with a melting curve centred around 55 degrees C. Energy calculations based on classical potential functions have been used to explore the three-dimensional structure of this polymer in helix and random by: The unfolded state and flexible linkers in the folded structure play essential roles in protein stability and folding and protein−protein interactions.

Intrinsic to these roles is the fact that unfolded proteins and flexible linkers sample many different conformations.

Polymer models may capture this and complement experiments in elucidating the contributions of the unfolded state and Cited by: Poly 8-bromoadenylic acid [poly(BBrA)] is the only known all-syn polynucleotide.
