  • Publication number: 20220220166
    Abstract: In order to improve aggregation property of a PPR protein, the A6 amino acid of the 1st PPR motif from the N-terminus (M1) is made more hydrophilic. Further, the A9 amino acid of M1 is made to be a hydrophilic amino acid or glycine. The A6 amino acid is preferably asparagine or aspartic acid, and the A9 amino acid is preferably glutamine, glutamic acid, lysine, or glycine. Proteins containing such a PPR motif as M1 motif may have not only improved aggregation property, but also high binding power to a target nucleic acid.
