Abstract:"Sexual aggregation involved in conjugative transfer of Enterococcus faecalis plasmid pAD1 is enhanced by the sex pheromone cAD1, which is excreted from recipient cells. A membrane-anchored 137 kDa protein is a pAD1-encoded aggregation substance designated asal, which is responsible for cell-cell contact and leads to the aggregation of cells. An AD74 protein is a proteolytic product corresponding to the N-terminal half of asal. The C-terminal of AD74 was identified as lysine at position 510 (K-510) by liquid chromatography/mass spectrometry (LC/MS): it indicates that asal is cleaved specifically between K-510 and G-511"
