Fig. 5 — The cryo-EM classes of the fibrillin microfibrils were recentered and refined to determine the structure of the fibrillin arm region. a, Cryo-EM structure of the arm region of fibrillin microfibrils. b, 2D class-averaged particles aligned to the fibrillin arm region reconstruction. Box size, 57 nm. c, Domains docked into the arm region reconstruction from TB2 to TB3, where the larger TB and hybrid domains correspond to the densities observed in electron microscopy images.
