(A, B) Stereoscopic views of the P3 RNase MRP RNA domain in complex with the RNase MRP/RNase P protein components Pop6 and Pop7. (A, B) Stereoscopic views of the P3 RNase MRP RNA domain in complex with the RNase MRP/RNase P protein components Pop6 and Pop7. The RNA nucleotides 29–50 are shown in red; nucleotides 59–78 are shown in green; the protein component Pop6 is shown in blue; the protein component Pop7 is shown in yellow; H0, H1, H2‐α‐helices; E0, E1, E2, E3, E4‐β‐strands; the positions of the N‐ and C‐terminal ends of the proteins are marked correspondingly. The disordered loops in Pop6 (residues 122–128) and Pop7 (residues 105–124) are symbolized by blue and yellow dots, respectively; the artificially introduced GAAA tetraloop linker connecting the nucleotides 29 and 78 in the crystallization construct is not shown.
