Competence-Stimulating Peptide-2

Competence-Stimulating Peptide-2 (CSP-2) is a 17-amino acid signal peptide produced by Streptococcus pneumoniae, with an EC50 of 50.7 nM for its compatible receptor ComD2. Competence-Stimulating Peptide-2 (CSP-2) can regulate bacterial phenotypes such as competence development, virulence, and biofilm formation through quorum sensing .
