Fig 3. Identification of peanut oleosins using peptide mass fingerprinting and N-terminal sequencing.

Peptides resulting from tryptic digestion were searched against the NCBInr database using the Mascot search engine. Bold letters indicate identified sequences by MALDI-TOF-MS, whereas underlined letters mark sequences obtained after N-terminal sequencing. The hydrophobic domains, not accessible to tryptic cleavage, are written in italics. The methionine residue, highlighted in grey, was not observed.
