Competence Inhibition by the XrpA Peptide Encoded Within the comX Gene of Streptococcus mutans

J. Kaspar, R. Shields, R. Burne

This study identifies XrpA, a peptide encoded within the comX gene of Streptococcus mutans, as a negative regulator of the ComRS system, affecting competence development and subpopulation behaviors.

Intercellular communication via the comX-Inducing Peptide (XIP) of Streptococcus mutans

J. Kaspar, S. A. M. Underhill, R. C. Shields, A. Reyes, S. Rosenzweig, S. J. Hagen, R. A. Burne

This study demonstrates that XIP from Streptococcus mutans functions as an intercellular signal, showing diffusibility and signaling without cell-to-cell contact, with cell lysis enhancing its release.
