AND GATE Sal+SupD+LacP+RBS(B0030)+T7ptag

This Device belongs to the SupD_T7ptag AND Gate family constructed by Peking University 2009 iGEM Team

This is a AND GATE in the Ecoli stain JM109. Use IPTG to induce the transcription of T7ptag and use salicylate to induce the transcription of supD. If the SupD tRNA exists, T7ptag can be translated into functional T7 polymerase, and otherwise the translation of T7ptag will come to stop because of some amber stop codon mutations in the T7ptag. The T7 polymerase will activate a T7 promoter.

Note: this AND gate make use of the lacI on the F plasmid of JM109, and because of the instability of the F plasmid, the leakage of lacP is significant. For improvement, a lacI generator can be assemble into it. This gate only works on low copy plasmid, such as pSB4K5, due to the lacI on the F plasmid.

This gate is only one of nine gates(K228852-K228860), which are different in the RBS of T7ptag.
