Figure 1 Intermolecular Crosslinking Analysis of Eukaryal RNase P RNA-tRNA Conjugates (A) 5′-arylazido-B. subtilis mature tRNAAsp crosslinks to eukaryal RNase P RNA. All reactions are identical, with the following exceptions, given for each lane: (1) the reaction contained E. coli RNase P RNA but was not exposed to UV, (2) the thio-containing tRNA was not coupled to the azidophenacyl bromide, (3) no RNase P RNA was added, (4) RNA complementary to E. coli RNase P RNA was included instead of E. coli RNase P RNA, (5) the reaction contained E. coli RNase P RNA, (6) the reaction contained H. sapiens RNase P RNA, (7) the reaction contained C. elegans RNase P RNA, (8) the reaction contained D. melanogaster RNase P RNA, (9) the reaction contained S. cerevisiae RNase P RNA, (10) the reaction contained S. pombe RNase P RNA, and (11) A. castellanii RNase P RNA was included. The S. pombe RNase P RNA-5′-arylazido tRNA conjugates were analyzed by primer extension. Unlabeled S. pombe RNase P RNA-tRNA conjugates were prepared, purified, and quantified as described in Experimental Procedures. Lanes 1 and 2 contain primer extension products using oligonucleotides 150R and 250R, respectively. Lanes C, U, A, and G correspond to sequencing reactions with noncrosslinked RNA template, and lane N is a control primer extension without dideoxynucleotides of unmodified S. pombe RNase P RNA. The termination sites of primer extension are indicated to the right of each gel. (B) 3′-arylazido mature RNA crosslinks to eukaryal RNase P RNA. Crosslinking and gel analysis are identical to (A). (C) The secondary structure of S. pombe RNase P RNA with the crosslink sites inferred from primer extension analysis indicated by arrows. An RNase P RNA structural nomenclature is described in Marquez et al., 2005. Solid arrows indicate sites in the S. pombe RNA that crosslink to the 5′ end of tRNA. Unfilled arrows indicate sites in the S. pombe RNA that crosslink to the 3′ end of tRNA. The dashed arrow indicates the unique site crosslinked by 5′-s6G-labeled tRNA. (D) Measurement of the dissociation constant (Kd) of arylazido mature B. subtilis tRNAAsp and S. pombe RNase P RNA. Crosslinking reactions were performed in the presence of increasing amounts of S. pombe RNase P RNA (0–2.0 × 10−5 M) incubated with 32P-labeled 5′-arylazido mature tRNA (228 nM). ● represents the fraction of tRNA bound to S. pombe RNase P RNA as assayed by radioactivity in the crosslinked band. The data were fit to the binding isotherm equation in Experimental Procedures. Molecular Cell 2006 24, 445-456DOI: (10.1016/j.molcel.2006.09.011) Copyright © 2006 Elsevier Inc. Terms and Conditions

Figure 2 Eukaryotic RNase P RNAs Are Affected Differently by Mg2+ and Are Less Stable than Bacterial RNase P RNAs (A) Various eukaryotic and bacterial RNase P RNAs (Aca, A. castellanii; Cel, C. elegans; Dme, D. melanogaster; Eco, E. coli; Hsa, H. sapiens; Sce, S. cerevisiae; Spo, S. pombe; Bst, B. stearothermophilus; and anti, control antisense E. coli) were folded and analyzed on 4.5% acrylamide 1× THE native gels containing 100 mM NH4OAc and various concentrations of Mg2+ (0 and 5 mM, shown left and right, respectively). Minor amounts of some eukaryotic RNase P RNAs migrated in oligomeric forms as seen with bacterial RNAs and previously reported in Buck et al., 2005 (data not shown). The relative change in RNA mobility between the 0 mM and 5 mM Mg2+ gels, normalized to the anti-Eco control RNA, is graphed below. Relative change in mobility is defined as: (d5mM / anti-d5mM) / (d0mM / anti-d0mM) − 1, where d5mM is the distance the RNA traveled from the well on the 5 mM Mg2+ gel, anti-d5mM is the distance the anti-Eco control RNA traveled from the well on the 5 mM Mg2+ gel, d0mM is the distance the RNA traveled from the well on the 0 mM Mg2+ gel, and anti-d0mM is the distance the anti-Eco control RNA traveled from the well on the 0 mM Mg2+ gel. (B) The thermal stability of various eukaryotic and bacterial RNase P RNAs was analyzed by TGGE. Gel conditions are as in (A), except containing 1 mM Mg2+. (Left) The E. coli and B. stearothermophilus RNase P RNAs melt at a higher temperature than S. pombe RNase P RNA. (Right) Similarly, the E. coli RNase P RNA melts at a higher temperature than either H. sapiens or S. cerevisiae RNase P RNA. Vertical lines indicate the transition temperature, where RNA tertiary structure unfolds. Molecular Cell 2006 24, 445-456DOI: (10.1016/j.molcel.2006.09.011) Copyright © 2006 Elsevier Inc.

Figure 3 Intramolecular Crosslinking Analysis of Circularly Permuted S. pombe RNase P RNAs cp69, cp118, cp140, and cp242 (A) Uniformly 32P-labeled photoagent-containing cpRNAs without (UV−) or with (UV+) 302 nm UV irradiation were analyzed by gel electrophoresis and autoradiography. The crosslinking reactions contained 1.0 μM photoagent-containing RNAs. The cpRNA crosslink reactions resulted in crosslinked bands, designated x1, x2, x3, etc. (B) Primer extension mapping of crosslinked RNAs was carried out with 5′-32P-labeled oligonucleotides complementary to S. pombe RNase P RNA (Supplemental Experimental Procedures). Primer extension mapping of some crosslinked RNAs indicated that they were circular molecules and uninformative (data not shown). Lanes C, U, A, and G correspond to sequencing reactions with noncrosslinked RNA template, and lane N is a control primer extension without dideoxynucleotides of unmodified S. pombe RNase P RNA. The primer extension reactions using the crosslinked species are indicated above each lane. The termination sites of primer extension are indicated to the right of the gel. The RNA sequence of the termination sites is shown on the left. Filled circles denote the actual crosslink sites which are one nucleotide 5′ to the primer extension termination sites. (C) Crosslinking sites in the RNA secondary structures are shown. The boxed G indicates the photoagent attachment site located at the 5′ end of the cpRNA. The circled bases in the secondary structure represent the corresponding crosslinking sites. Arrowheads indicate the direction of the crosslinks.

Figure 4 Commonalities in Structure and Function between the Crystal Structure of Bacterial RNase P RNA and the Modeled Eukaryal RNase P RNA (A) Coaxial stack representation of the secondary structures of B. stearothermophilus and S. pombe RNase P RNAs. The RNA that is homologous between B. stearothermophilus and S. pombe RNase P RNAs is represented as blue; nonhomologous RNA is colored gray; and RNA not represented in the B. stearothermophilus crystal structure is colored black in both molecules. Arrows indicate the 5′ to 3′ direction. Sites of 5′ tRNA crosslinking are represented as red spheres. B. stearothermophilus long-range tertiary interactions between helices are indicated by dashed lines, while homologous interactions are lacking in S. pombe RNA. The main site of 3′ tRNA crosslinking (P15) in B. stearothermophilus RNA is colored gold. A main site of 3′ tRNA crosslinking in S. pombe RNA is the P3 bulge loop, which, while not homologous to bacterial P15, is also colored gold. (B) Tertiary structure ribbon models of B. stearothermophilus and S. pombe RNase P RNAs, as colored in (A). S. pombe RNase P RNA nucleotides 136–185 are not included in the modeling because of the inconsistency of the results between cp140 crosslink sites and the crystal structure of T. maritima RNase P RNA. The double-headed arrow indicates the long-range tertiary interaction between P5.1 and P15.1. The structure of P3 bulge loop and P3b could not be reliably inferred from the bacterial structure and therefore has not been modeled. However, the location of 5′ and 3′ tRNA crosslinks (indicated by red spheres and regions highlighted in gold) suggests that these regions of the S. pombe RNA are in close proximity, consistent with the model. (C) Side view of B. stearothermophilus and S. pombe RNase P RNAs. In the side view, the coaxial stack of P19, P2, and P3 is in the forefront. The general position of tRNA is indicated by a bracket.
