Figure 6. — Molecular details of the modeled four-way junction. (A) Detailed view of the four-way junction from the modeled monomeric RNA. The four-way junction is formed by base stacking between the P1 (blue) and P3 (yellow) stems and between the P2 stem (cyan) and S3 (green) stems. Base pairs between A51 and U55 and between C52 and G65 are labeled. (B) Molecular details of the base pairs highlighted in (A). Electron density is from a composite omit map of the crystal structure at 1σ contour level.
