Structural and Mechanistic Basis of FapB Accessory Functional Amyloid Assembly in Pseudomonas

Abdulkadir Tunc, Chang‐Hyeock Byeon, Jan-Hannes Schäfer, Kasper Holst Hansen, Danielle Ann Grotjahn, Maria Andreasen, Rejaul Hoq, James F. Conway, Ümit Akbey

This study determines the structural and mechanistic basis of FapB amyloid assembly in Pseudomonas, showing it forms cross-β-solenoid fibrils and interacts with FapC fibrils.
