abstract：:Pentatricopeptide repeat (PPR) proteins are helical-repeat proteins that offer a promising scaffold for the engineering of proteins to bind specified RNAs. PPR tracts bind RNA in a modular 1-repeat, 1-nucleotide fashion. An amino acid code specifying the bound nucleotide has been elucidated. However, this code does no...
