PRORP1 PPR motifs use distinct mechanisms for tRNA recognition. (A) Recognition of ψ55 by PRORP1 repeat 3. (B) Recognition of U2 by PPR10 repeat 2 (PDB ID: 4M59). (C) Recognition of G19 by PRORP1 repeat 2 (PDB ID: 6LVR). (D) Differences in specific RNA recognition by PRORP1 and PPR10. RNA-interacting residues in PPR motifs 1–4 of PRORP1 and PPR10 are shown. Nucleotides recognized are shown below and connected by a yellow line. Individual recognition modules are boxed with PRORP1 colored green and PPR10 colored blue.
