title: Streptococcus faecalis sex pheromone (cAD1) response: evidence that the peptide inhibitor excreted by pAD1-containing cells may be plasmid determined.
abstract: Streptococcus faecalis strains harboring the conjugative plasmid pAD1 excrete a small peptide, iAD1, which inhibits the sex pheromone cAD1. Studies making use of the host strain Streptococcus faecium 9790, which normally does not excrete peptide pheromones, suggest that iAD1 may be determined directly by pAD1.
