peptide de novo sequencing is the analytical process that derives a peptide's amino acid sequence from its tandem mass spectrum (MS/MS) without the assistance of a sequence database. It is in contrast to another popular peptide identification approach - "database search", which searches in a given database to find the target peptide. A clear advantage of de novo sequencing is that it works for both database and novel peptides.
