Identification of ComW as a new component in the regulation of genetic transformation in Streptococcus pneumoniae.

Regulation of competence for genetic transformation in Streptococcus pneumoniae depends on a quorum-sensing system, genes involved in DNA uptake and recombination and a link between these two gene sets. The alternative sigma factor ComX provides this link. ComE, the response regulator of the quorum-sensing system, is required for expression of ComX and… CONTINUE READING
