M. Kleerebezem et al., A two-component signal-transduction cascade in Carnobacterium piscicola LV17B: two signaling peptides and one sensor-transmitter, PEPTIDES, 22(10), 2001, pp. 1597-1601
In the lactic acid bacterium Carnobacterium piscicola LV17B a peptide-phero
mone dependent quorum-sensing mode is involved in the regulation of bacteri
ocin production. Bacteriocin CB2 was identified as an environmental signal
that induces bacteriocin production. Here, we demonstrate that a second 24
amino acid peptide (CS) also induces bacteriocin production. Transcription
activation of several carnobacteriocin operons is triggered by CB2 or CS vi
a a two-component signal transduction system composed of CbnK and CbnR. (C)
