Cryo-EM Structures of Sunflower Amyloid Fibrils Reveal Two Distinct Disulfide‑Linked Assembly Modes.
Sunflower meal is an abundant but underutilized plant protein source. Recent studies have demonstrated that its amyloid fibrils exhibit exceptional functional properties, yet the atomic-level structural basis remains unknown. The first cryo‑electron microscopy (cryo‑EM) structures of sunflower amyloid fibrils prepared...
