HRT2 prenyltransferase from Hevea Brasilianis (ara promoter with araC: arabinose inducible) This part encodes the rubberproducing prenyltransferase from the rubber tree Hevea brasiliensis. It uses isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) as substrates to produce cis-1,4 polyisoprene natural rubber.

The part is designed to express the enzyme when induced with arabinose under glucose scarce conditions. Arabinose binds the ara promoter regulator, AraC, and arabinose bound AraC then activates the transcription of the ara promoter.

The coding region of araC with a constitutively active promoter, a strong RBS and a efficient terminator was added to the part to see if the expression from the ara promoter would be elavated compared to a similar construct (BBa_K1088024) not bearing the araC device.

Using Northern blot technique it was proved that the construct in E. coli K-12 MG1655 doesn't express the prenyltransferase when grown without arabinose. Upon addition of arabinose to the media prenyltranferase mRNA was detected. The addition of the araC device did not prove to elevate the expression level. See experince for more details.
