| + | ===感度差による応答時間の差=== |
| + | 任意の順番と、delay-timeをもった遺伝子発現を実現するために、バクテリア間の細胞間通信、クオラムセンシングを利用する。クオラムセンシングでは、応答閾値を超えるAHLが蓄積されたとき初めて、目的遺伝子の発現がおこる。AHL情報がじゅうぶんゆっくり蓄積するとき、ひとつのAHL送信装置に対して、感度の異なる複数の受信装置によってさまざまな出力装置を独立に起動すれば、感度の高いAHL 受信機ほど先に起動する。 |

| + | LuxIのつくるAHLに対して、感度差による応答時間差は、2つの方法で実現することができる。 |

| + | #クロストークを使う場合 |
- | ::*[http://partsregistry.org/Part:BBa_C0076| BBa_C0076](2007)
| + | :AHL=Acyl-homoserine Lactoneには、そのアシル基が異なる種類がある。luxIが合成するAHLは、3-oxo-hyxanoyl-Homoserine Lactone (=OHHL)であり、3-oxo-dodecanoyl-homoserine Lactone(=ODHL)や、butyryl-homoserine Lactone(=HHL)が存在する。それぞれ、合成酵素はLasI、RhlI(ともにシュードモナス由来)と呼ばれる。このほかのAHL分子と、その合成酵素を以下に示した。これらのAHL分子は、アシル基のみが異なるため、一定の割合でLuxRと相互作用する(cross-talkする)。たとえば、OdHLとLuxRとのcross-talk(LasI-LuxR)は、OHHLとLuxRの場合(LuxI-LuxR)の1/20である。AHL分子の蓄積速度が一定ならば,luxI-LuxR/Pluxよりも20倍遅くスイッチが入ることとなる。 |

任意の順番と、delay-timeをもった遺伝子発現を実現するために、バクテリア間の細胞間通信、クオラムセンシングを利用する。クオラムセンシングでは、応答閾値を超えるAHLが蓄積されたとき初めて、目的遺伝子の発現がおこる。AHL情報がじゅうぶんゆっくり蓄積するとき、ひとつのAHL送信装置に対して、感度の異なる複数の受信装置によってさまざまな出力装置を独立に起動すれば、感度の高いAHL 受信機ほど先に起動する。
