This part is a fusion of Spinach2.1 desinged by the iGEM Team DTU Danemark. By cloning the part into the RFC 110 transcription is possible using T7 RNA Polymerase. Cleavage is achieved by the HDV.
Proporties of the ATP Aptamer Spinach2
In our project we generated new biobricks. The first one (BBa_K1614012) contains a Spinach2 aptamer that was fused to the ATP Aptamer. This device was applied to detect the small molecule ATP during in vitro reactions such as in vitro transcription. This BioBrick is the first fluorescent ATP sensor. Experiments have shown that the ATP Aptamer Spinach2 is able to detect ATP and can even sense dynamic changes in ATP concentration during biochemical reactions like in vitro transcriptions. Compared to the other ATP Aptamer Spinach2 variations the ATP Aptamer Spinach2 has the lowest fluorescence shown in the spectrum. Even though the ATP Aptamer Spinach2 was tested during the in vitro transcription reaction, it showed less sensitivity than the ATP Aptamer JAWS1 Spinach2.
