(a) CryoEM model of mouse heavy-chain apoferritin (PDB code: 8rqb), focusing on Fe 201 in chain A, and corresponding experimental map (EMDB code: 19436) contoured at ±1.5 units. (b) Radial components of the experimental cryoEM map around Fe (blue curve), exact density (red curve) and its finite-resolution image computed using (8)[link] (orange curve), and of several maps calculated for an isolated Fe atom. All maps normalized by their values at the origin (maximum value). See the main text for details.
