  "id": "MLC-T-CHM-008610",
  "term": "Peptide sequence tag",
  "field": "Chemistry",
  "definition": "A short, experimentally determined amino acid sequence derived from the fragmentation spectrum of a peptide, combined with the mass of the precursor ion and the mass of a terminal fragment. This tag provides a unique identifier that can be used to search protein databases for homologous sequences. It is a powerful tool for protein identification and characterization.",
