Competence-stimulating peptide

Competence-Stimulating Peptide-2 (CSP-2) is a quorum sensing signal peptide synthesized by Streptococcus pneumoniae. ComD2, a compatible receptor of CSP-2, exhibits an EC 50 value of 50.7 nM.

Competence-Stimulating Peptide-12261, a sixteen-peptide fragment, is a part of competence-stimulating peptide (CSP).

Competence-Stimulating Peptide-12261 acetate (1235882-91-3 free base) 是感觉刺激肽的片段，是一种抑制胚管 (GT) 形成的群体感应分子。

CSP1 is a highly potent and selective agonist of the ComD1 receptor, exhibiting an IC50 value of 10.3 nM. It represents a major variant of competence-stimulating peptide (CSP) and plays a crucial role in regulating the genetic transformation of S. pneumoniae through modulation of quorum sensing (QS). Additionally, CSP1 possesses antibacterial activity, further enhancing its potential as an effective antibacterial agent.
