Hydroxylation of Pro residues in the amino acid sequence of At2g10940 encoding a protein homologous to non-specific lipid transfer protein. The amino acid sequence of At2g10940 is written from left to right and from top to bottom. The predicted peptide signal is indicated in light blue. The Pro-rich domain is displayed in order to emphasize repetitive sequences and tryptic peptides (one per line). On the left side, predicted Pro (P) and Hyp (O) residues are in pink and green, respectively. On the right side, observed Pro and Hyp residues at unexpected positions are underlined. For each peptide, the number between brackets corresponds to its frequency of occurrence, expressed as a ratio between the number of observed peptides and the total number of sequenced peptides. The numbers inside stars allow the comparison between the predicted/observed peptides (on the left side) and the corresponding observed Pro/Hyp peptide variants (on the right side).
