FIGURE 1.
Bacterial RNAse P RNA structures. (A) Crystal structures of RNase P RNA from B. stearothermophilus (B-type) and T. maritima (A-type). Paired elements of the structure (P1, P2, etc.) are labeled in the order of their occurrence from the 5′-end. (B) Secondary structure of the B-type RNase P RNA (B. stearothermophilus). Dashed lines mark independently folding structural domains. Solid lines indicate long-range docking interactions. Helical elements of the structure are labeled and colored according to A. (C) Secondary structures of the A-type RNase P RNAs, from E. coli and A. tumefaciens.
