This device expresses the dxs gene derived from B. subtilis, and is under the control of the lactose promoter. The device is meant for us to increase the amount of IPP and DMAPP in the cell. Plac function characterized by GFP fusion using FACS and growth experiment.

BBa_K1088012 Plac-dxs(E. coli)
This device expresses the dxs gene (BBa_K118000) derived from E. coli, and is under the control of the lactose promoter. The device is meant for us to increase the amount of IPP and DMAPP in the cell. Has been sequenced.
Regulable production devices
BBa_K1088013 Pcon-lacI:LVA-term-Plac-dxs(B. subtilis)
This device expresses the dxs gene derived from B. subtilis, and is under the control of the lactose promoter. The device is meant for us to increase the amount of IPP IPPIsopentenyl pyrophosphate and DMAPP DMAPPDimethylallyl pyrophosphate in the cell. Furthermore the lacI:LVA gene with a constitutive promoter was added to optimize the expression control through the lactose promoter. Natural LacI proved to be more efficient, though. Has been sequenced.

BBa_K1088014 Pcon-lacI:LVA-term-Plac-dxs(E. coli)
This device expresses the dxs gene derived from E. coli, and is under the control of the lactose promoter. The device is meant for us to increase the amount of IPP IPPIsopentenyl pyrophosphate and DMAPP DMAPPDimethylallyl pyrophosphate in the cell. Furthermore the lacI-LVA gene with a constitutive promoter has been added to optimize the expression control through the lactose promoter.

BBa_K1088015 Pcon-lacI:LVA-term-Plac-dxs(B. subtilis)-ispG
This device expresses the dxs gene derived from B. subtilis, and is under the control of the lactose promoter.The device was build to increase the amount of IPP IPPIsopentenyl pyrophosphate and DMAPP DMAPPDimethylallyl pyrophosphate in the cell if the first rate limiting step was overcome. Furthermore the lacI:LVA gene with a constitutive promoter has been added to optimize the expression control through the lactose promoter (see results for description LacI-LVA efficiency).

BBa_K1088016 Pcon-araC-term-Para-HRT2-(3xFLAG)
This device expresses the HRT2 gene derived from Hevea brasiliensis, and is under the control of the arabinose promoter. The device was made to enable the bacteria to polymerize IPP IPPIsopentenyl pyrophosphate and DMAPP DMAPPDimethylallyl pyrophosphate into rubber. Furthermore the arabinose promoter regulator AraC has been added to check if it would enhance the expression control of arabinose promoter . It did not seem to improve expression control. Has been sequenced. AraC and Para function characterized by Northern blot and HRT2 function characterized by H1-NMR.

BBa_K1088024 Para-HRT2-(3xFLAG)
This device expresses the HRT2 gene derived from Hevea brasiliensis, and is under the control of the arabinose promoter. The device is meant to enable the bacteria to polymerize IPP IPPIsopentenyl pyrophosphate and DMAPP DMAPPDimethylallyl pyrophosphate into rubber. Has been sequenced. AraC and Para function characterized by Northern blot and HRT2 function characterized by H1-NMR.

BBa_K1088027 Pcon-lacI(N)-Plac-dxs (B. subtilis)
This device expresses the dxs gene derived from B. subtilis, and is under the control of the lactose promoter. The device is meant for us to increase the amount of IPP IPPIsopentenyl pyrophosphate and DMAPP DMAPPDimethylallyl pyrophosphate in the cell. Furthermore the lacI gene with a constitutive promoter was added to optimize the expression control through the lactose promoter. This addition proved to have the most efficient expression control. LacI and Plac function characterized by GFP fusion using FACS and growth experiment.
