| BBa_K1886000 | Device | pluxR->luxS | luxS is controlled by pluxR promoter. luxS is a kind of DPD synthetase, which could produce DPD (4,5-dihydroxy 2,3-pentanedione) under the cooperation of Pfs enzyme. DPD exists widely in Gram-negative bacteria and Gram-positive bacteria as the signaling factor for quorum sensing, in order to complete the information transfer process within different kinds of bacteria. |
| BBa_K1886001 | Device | AHL single-cycled oscillation pluxL-luxR-pluxR-luxI(LAA tag)-pluxL-luxR-pluxR-aiiA(LAA tag) | This circuit is composed of the constitutive promoter -- broken Ptet and membrane protein cph8. Under dark conditions, protein cph8 could transfer its phosphoryl group to intracellular protein ompR (ompR is native protein carried by E.coli), and this process could be inhibited by 650-nm light. |
| BBa_K1886002 | Device | AHL,DPD double-cycled oscillation pluxL-luxR-pluxR-luxI(LAA tag)-pluxL-luxR-pluxR-aiiA(LAA tag)-luxpR-luxS | Two molecules of luxR binds with AHL (catalyzed by luxI), and this compound will promote the activity of pluxR. pluxR controls the expression of gene aiiA , encoding the enzyme which degrades AHLs. And all of these form an AHL single-cycled oscillation. |

Under dark conditions, protein cph8 could transfer its phosphoryl group to intracellular protein ompR (ompR is native protein carried by E.coli), and this process could be inhibited by 650-nm light. |
Parts for AND Logic Gate

|---|---|---|---|
| BBa_K1886007 | Device | AND GATE-input | This is the input part of AND GATE. After being induced by IPTG, plac promoter activates the expression of T7 RNA polymerase which contains two amber mutations (T7 ptag) . After being induced by L-arabinose, pBAD promoter activates the expression of a special tRNA (supD), which is used to identify amber mutation. In the wild-type E.coli, amber mutation will inhibit the translation of T7 RNA polymerase. Therefore, only when the two inputs exist together, T7 RNA polymerase can be expressed, and then T7 promoter can be activated to express the downstream gene. |
