Quorum - sensing systems can be divided into two paradigmatic classes : luxi / luxr - type quorum - sensing systems in gram - negative bacteria which produce acyl - homoserine lactone ( ahl ) autoinducers , and oligopeptide / two - component - type quorum - sensing ciruits in gram - positive bacteria which produce autoinducing peptide ( aip ) autoinducers . in contrast to the two paradigmatic quorum - sensing systems , vibrio harveyi produces and responds to an ahl - type autoinducer termed ai - 1 and a novel signal molecule named ai - 2 Qs系統可分為兩種典型的類型,即革蘭氏陰性細菌的luxi luxr型qs系統,革蘭氏陽性細菌的寡肽雙組分型qs系統,分別以酰基高絲氨酸內酯( acyl - homoserinelactones , ahl ) 、寡肽( autoinducingpeptide , aip )為信號分子。
