Figure 4

Experimentally validated aa residues of the plant PTS1 motif. Tripeptide residues identified as novel plant PTS1 tripeptides in this study (Q at pos. -3 and D at pos. -2) are indicated by white boxes. According to experimental data and PWM model predictions [16], at least two of the seven high-abundance residues of predicted high targeting strength ([SA][KR][LMI]>, black boxes) must be combined with one low-abundance residue (grey or white boxes) to yield functional plant PTS1 tripeptides (x[KR][LMI]>, [SA]y[LMI]>, [SA][KR]z>).
