ABSTRACT A search for homologs of the Bacillus subtilis PhoP response regulator in the
group A streptococcus (GAS) genome revealed three good candidates. Inactivation of one of …

Gram-positive and gram-negative bacteria use quorum sensing to coordinate population
behavior. In several streptococci, quorum sensing mediated by competence-stimulating …

In Streptococcus mutans, both competence and bacteriocin production are controlled by
ComC and the ComED two-component signal transduction system. Recent studies of S …

In many streptococci, including Streptococcus mutans, genetic competence is regulated by a
quorum sensing system mediated by a competence stimulating peptide (CSP) pheromone …

The genetic variability in comC, the gene encoding the quorum-sensing molecule,
competence-stimulating peptide (CSP) in Streptococcus mutans is reported. Seven comC …

Streptococcus mutans displays complex regulation of natural genetic competence.
Competence development in S. mutans is controlled by a peptide derived from ComS (XIP); …

Competence for genetic transformation in the genus Streptococcus depends on an
alternative sigma factor, σX, for coordinated synthesis of 23 proteins, which together …

Streptococcus gordonii is a primary colonizer of the multispecies biofilm on tooth surfaces
forming dental plaque and a potential agent of endocarditis. The recent completion of the …

Streptococcus mutan s develops competence for genetic transformation in response to
regulatory circuits that sense at least two peptide pheromones. One peptide, known as CSP …
