Figure 6
(a) Superhelical structure of apo designer P-class PPR protein (PDB entry 4ozs); one helical repeat is shown in red (adapted from Marzano et al., 2024  ). (b) Superhelical structure of designer P-class PPR protein bound to RNA (PDB entry 6een). (c) Canonical binding of PPR proteins with the nucleotide bases guanine (G), adenine (A), uracil (U) and cytidine (C). The fifth and 35th amino-acid residues in each repeat are highlighted as sticks. The hydrogen-bonding interaction is shown in blue. Water molecules are depicted as red spheres (adapted from Shen et al., 2016). (d) Noncanonical binding of PPR10 protein, showing hydrogen bonding between adenine (A) and aspartate (D) 630 and between cytidine and serine (S) 714 (adapted from Yin et al., 2013). (e) Interaction of THA8 dimer proteins with Zm4 RNA nucleotide base G. Hydrogen bonds are shown as blue dashed lines. The amino acids and nucleotide bases are shown as sticks (adapted from Ke et al., 2013). |
