From: Non-canonical peroxisome targeting signals: identification of novel PTS1 tripeptides and characterization of enhancer elements by computational permutation analysis

Figure 6

Computational permutation analysis of three Arabidopsis proteins carrying non-canonical PTS1 domains. The eleven residues upstream of the novel non-canonical PTS1 tripeptides (pos. -4 to −14) of three Arabidopsis proteins (1, QRL>, At1g18700.2; 2, SQM>, At5g45160.1; 3, SDL>, At5g03730.1) were computationally permuted one by one in all possible 209 combinations (11 x 19 = 209) and the changes in PWM prediction scores investigated. (A) Pattern of PWM score range windows of permuted sequences, (B) total PWM score optimization potential and (C) relative PWM score optimization potential in percentage. The absolute magnitude of the PWM score range window on the y axis and its positioning relative to the PWM prediction score of the original Arabidopsis QRL > sequence (grey line) indicates the absolute optimization potential of a position-specific residue (A). In A1-C1 the PWM prediction score of the original Arabidopsis sequences is indicated by a grey line. Important residues that are predicted to enhance peroxisome targeting are shaded in grey.
