BBa_J100295 1 BBa_J100295 DB Biosensor + NarX 2016-07-12T11:00:00Z 2016-07-13T03:11:05Z narGHJI operon This construct is built by modifying DB Nitrate Biosensor (J100260), which is built by inserting narG promoter sequence into pClone Red (J119137) through GGA. There are binding sites for activators NarL on the narG promoter. NarX, the sensor kinase, is known to phosphorylate NarL, which is the response regulator, so we inserted the NarX gene into the plasmid replacing the reverse GFP, hoping that will increase NarL binding on the promoter. Also sensor kinase mRNAs are synthesized efficiently but they rapidly degrade. Therefore we inserted a 5' terminal stemloop upstream of the NarX gene to reduce mRNAs degradation by RNase E. In conclusion, we removed the GFP reverse and inserted a complex with a transcription terminator, a promoter, a stemloop, a RBS, and the NarX gene. The goal is that nitrate induces the promoter, then RFP is expressed when nitrate is present. However, this promoter does not induce RFP production when nitrate is present. false false _578_ 23989 23989 9 false / false Shuk Hang Li igem2sbol 1 iGEM to SBOL conversion Conversion of the iGEM parts registry to SBOL2.1 Chris J.
