Fig. 6: Substrate binding pockets in RNase MRP and RNase P.
From: Cryo-EM structure of catalytic ribonucleoprotein complex RNase MRP
Protein components are color coded according to Fig. 2. RNase MRP and RNase P RNAs are shown as cartoons in black. The substrate pre-tRNA in the substrate binding pocket of RNase P21 (b) is shown as a cartoon in yellow. The location of the scissile bonds is shown by yellow spheres (a, b). The locations of the RNase MRP nucleotides that crosslink to substrates20 are shown as spheres in cyan (a).
