Popis: The valine-activation domain-encoding portion of the srfA locus (srfA-d4) is not only involved in the non-ribosomal synthesis of surfactin, but is also required for the regulation of competence development. In this study we show that impairment of the adenylation activity of the valine-activating domain did not affect competence development. Deletion analysis and complementation studies delineated the competence-required portion of srfA-d4 to a 168 bp fragment, which contains a small open reading frame (ORF), designated comS, encoding a polypeptide of 46 amino acids, embedded within, but translated in, a frame different from that of srfA-d4. Introduction of an amber mutation in the comS-coding frame prevented competence development, demonstrating the involvement of comS in this prokaryotic specialization process.
