Fig. 3: Cryo-EM structure of the POWV class 2 xrRNA.
From: Tick-borne flavivirus exoribonuclease-resistant RNAs contain a double loop structure
A Local resolution map of the scaffolded POWV xrRNA. Resolution is colored as denoted in the inset key B. Cryo-EM map of the POWV xrRNA, the locations of secondary structure features are indicated. C Secondary structure diagram of the POWV xrRNA, colored to match D and E. D Structural model of the POWV xrRNA colored to match C. The yellow dashed backbone represents 9 nucleotides that were not visible in the map and hence not built. Structural features are labeled. E Comparison of POWV and TABV ring topologies colored corresponding to C.
