Cryo-electron microscopic (cryo-EM) analysis of Rps20Δloop pre-40S particles. Surface views of cryo-EM maps of Ltv1-purified wild-type pre-40S particles16 (left panel) and the Rps20Δloop pre-40S particles (central panel: C1-S20Δloop particles; right panel: C2-S20Δloop particles). Assembly factors and r-proteins of interest have been segmented and colored; the arrowhead next to the C2-S20Δloop map indicates missing density in the platform region compared to the other maps
