Research output: Contribution to journalArticlepeer-review


The trace proteome of white-wine vinegar has been identified via capture with home-made combinatorial peptide ligand libraries under conditions mimicking reverse-phase capture, i.e. at pH 2.2 in presence of 0.1% trifluoroacetic acid. A total of 27 unique gene products have been identified, of which 10 specific of the database Vitis vinifera, 13 found in the general database Uniprot_viridiplantae and 4 in Swiss Prot_all entries. The most abundant species detected, on the basis of spectral counts, appears to be the whole genome shotgun sequence of line PN40024, scaffold_22 (a protein of the glycosyl hydrolase family). Curiously, up to the present, no information had been available on vinegar proteome.
