Modular Adda riboswitch containing Tuner A
Design
Background of 2019 OUC-China's project——RiboLego
Due to context-dependent performance and limited dynamic range, the widespread application of riboswitches is currently restricted. By replacing its original ORF with a new one, the structure of an aptamer domain can be subtly disrupted, resulting in a loss of ligand response. So riboswitch is still not be considered as a ‘plug and play' device. To tackle these problems, our project focuses on a standardized design principle to be used for modular and tunable riboswitch. The modular riboswitch we defined consists of the original riboswitch, Stabilizer and Tuner. Stabilizer can protect the structure of riboswitch from damage while Tuner can reduce the expression probability of fusion protein and make improvement of riboswitch function.
The construction of this part
We defined a modular riboswitch to include the original riboswitch, Stabilizer and Tuner. To validate our design guideline, we employed a activating Adda riboswitch, which can regulate the expression of adenosine deaminase by binding 2-aminopurine in Vibrio vulnificus.The first 150bp of adenosine deaminase was chosen as Stabilizer of Adda riboswitch because our docking matrix suggested that a normal riboswitch structure would be observed when using this length of Stabilizer. This part was modular Adda riboswitch containing the original riboswitch, Stabilizer and Tuner A.
