The final map was generated using homogeneous refinement against the ab-initio map with I symmetry imposed, per-particle defocus optimization, per-group CTF parameterization, spherical aberration fitting enabled, tetrafoil fitting enabled, anisotropic magnification fitting enabled, and Ewald sphere correcting enabled with a negative curvature sign.

A starting model of a single protomer was generated using AlphaFold 3, and individual protomers were fit into the volume of an asymmetric unit using UCSF ChimeraX v 1.8. The model containing a single asymmetric unit consisting of three protomers was then manually refined using Coot v 0.9.8.1, followed by real-space refinement in PHENIX v 1.20.1-4487-000. Non-crystallographic symmetry (NCS) operators were then applied to generate a complete NCS-expanded shell, which was refined against the map using PHENIX real-space refinement.
