Extended Data Fig. 2: Cryo-EM map quality and model to map fitting.
From: Cryo-EM structure of an active bacterial TIR–STING filament complex
a, Fourier shell correlation (FSC) curves versus resolution (1/Å) of indicated EM maps. Resolution was estimated at FSC = 0.143. b, Model versus map FSC curves. c, Examples of map to model fit quality for select regions of the single fibre SfSTING complex with c-di-GMP (contoured at 7σ). d, Overall density map for filament protomer SfSTING dimer. STING CBD in orange and TIR in pink. Transparent density with dimer model (contoured at 7σ, right). Linker region sequence (144–176) highlighted in green and boxed.
