Staufer et al. provide a protocol for preparation of synthetic minimal virions (MiniV) of SARS-CoV-2, mimicking viral structure and allowing for precise investigation of receptor binding mechanism. They find that the highly conserved free fatty acid binding pocket (FABP) can function as an allosteric regulator, enabling adaptation of immunogenicity via binding of proinflammatory free fatty acids and mediating the spike open to-closed equilibrium.
