An Enterococcus faecalis plasmid, pAM373, has a high frequency of transfer in a liquid medium when induced by a recipient-produced sex pheromone, cAM373. The sex pheromone inhibitor against cAM373, termed iAM373, was isolated from a culture supernatant of E. faecalis harboring pAM377 (= pAM373::Tn917), and its structure was identified as a heptapeptide, H-Ser-Ile-Phe-Thr-Leu-Val-Ala-OH).
粪肠球菌质粒pAM373在由受体产生的性信息素cAM373诱导时，在液体培养基中有较高的转移频率。从携带pAM377（=pAM373::Tn917）的粪肠球菌培养上清液中分离出针对cAM373的性信息素抑制剂，称为iAM373，其结构被鉴定为一种七肽，H-丝氨酸-异亮氨酸-苯丙氨酸-苏氨酸-亮氨酸-缬氨酸-丙氨酸-OH）。
