A Combinatorial Amino Acid Code for RNA Recognition by Pentatricopeptide Repeat Proteins

Nucleotides That Align with the Most Frequent Combinations of Amino Acids at Positions 6 and 1′.

Nucleotides aligned with each 6/1′ combination in the alignments in Figure S1 were used to construct sequence logos [30]. Only P motifs were used in this analysis. Each logo shows the aligned nucleotide (0) and the preceding (−1) and succeeding (+1) nucleotides. 25, 23, 102, 86 and 16 alignments were used to generate the T6N1′, T6D1′, N6D1′, N6N1′ and N6S1′ logos, respectively.
