Part:BBa_K4438701
P4G13_trigger_1_w/oPol
P4G13_trigger_1_w/oPol is single-stranded DNA having 38 nucleotides. Figure 1B) shows the secondary structure and minimum free energy. At the 5’ end, a few bases are complementary to P4G13_aptamer (<partsinfo>BBa_K4438700</partsinfo>). The middle region consists of a full ssDNA sense T7 promoter sequence and at the 3’ end, there are a few bases of ssDNA sense broccoli sequence.
Usage and Biology
Figure 2D) Shows the secondary structure of both the parts hybridised at 37° Celsius. The hormone binds with P4G13_aptamer (<partsinfo>BBa_K4438700</partsinfo>) with high affinity [1] and displaces the P4G13_trigger_1_w/oPol (<partsinfo>BBa_K4438701</partsinfo>).
This part has complete complementarity with the part P4G13_Target_1 (<partsinfo>BBa_K4438702</partsinfo>). T7 polymerase binds and in-vitro transcription of the duplex forms multiple broccoli light-up aptamers.
All three parts can be used to detect different concentrations of progesterone.
