Abstract excerpt
Bacteria use quorum-sensing signals or autoinducers to communicate. The signals in Gram-positive bacteria are often peptides activated by proteolytic removal of an N-terminal leader sequence. While investigating stimulation of antimicrobial peptide production by the Streptococcus mutans synthetic competence stimulating peptide signal (21-CSP), we found a peptide similar to the 21-CSP, but lacking the three...
