Extended Data Fig. 4: Model fit and Ramachandran plot.
From: InsP6 binding to PIKK kinases revealed by the cryo-EM structure of an SMG1–SMG8–SMG9 complex
Quality of the structural model built de novo in the cryo-EM map. (a) Representative regions of the SMG1c and surrounding electron density are shown. (b) Ramachandran plot of the main-chain φ, and ψ conformational angles of the SMG1-SMG8-SMG9 atomic model. Areas of favored φ and ψ combinations are defined in dark blue (see also Supplementary Table 1).
