主权项

1. An isolated peptide comprising at least 7 amino acids and at most 24 amino acids, wherein the isolated peptide has an amino acid sequence as set forth in SEQ ID NO: 3 when the isolated peptide is 24 amino acids long and the isolated peptide comprises a portion of SEQ ID NO: 3 including at least PYFTGCL (SEQ ID NO: 128) when the isolated peptide includes 23 amino acids or less, and wherein said peptide induces or increases competence in a S. thermophilus strain.
