Part:BBa_R0080
Promoter (AraC regulated)
AraC operator, truncated to include araO1, araI1, araI2, c-amp1, and c-amp2 sites. This operator should *activate* transcription in the presence of AraC or the simple sugar [http://openwetware.org/wiki/Arabinose arabinose]
b/c the operator lacks the araO2 site, there should not be araC-mediated repression.
Usage and Biology
araC binding region from E.coli

Summary: We tested expression of this part in E.coli, and corrected the founction description of this part.
Methods and Practices
We used the circuit of BBa_K1532008 to test the function of this part, the sequence and features of the part BBa_K1532008 is as follows:
Fluorometric measurement were processed with Fluoroskan(R) Ascent FL from ThermoTM using the filters of 485nm and 538nm. The E.coli to be tested was cultured in liquid LB media containing 35μg/mL chloramphenicol to OD1.6, than split into 96 well plates (from ThermoTM) by 150μL/well. The plate was then put into the Fluoroskan(R) Ascent FL and cultured in 25℃ and background shake of 90rpms. The Fluorometric measurement was processed with the interval time of 10 minutes.
The layout of the plate is as follows:
//direction/forward
//promoter
//regulation/positive
//rnap/prokaryote/ecoli/sigma70
