Abstract

Enterococus faecalis plasmid pAM373 encodes a mating response to the sex pheromone, cAM373, which is secreted from pAM373-free E. faecalis. cAM373-like activity was detected in a culture filtrate of Staphylococcus aureus. The major active substance, termed staph-cAM373, was isolated, and its structure was identified as a H-Ala-IIe-Phe-IIe-Leu-Ala-Ala-OH heptapeptide.

摘要

粪肠球菌质粒pAM373编码对性信息素cAM373的交配反应，cAM373由不含pAM373的粪肠球菌分泌。在金黄色葡萄球菌的培养滤液中检测到了cAM373样活性。分离出主要活性物质，称为葡萄球菌-cAM373，并确定其结构为H-Ala-Ile-Phe-Ile-Leu-Ala-Ala-OH七肽。
