T7 polymerase stage 1 with nMag.


Usage and Biology

In our project, we divided T7 RNA polymerase into two parts, respectively called T7NT (BBa_K3447008) and T7CT (BBa_K3447007) and attached on the nMag and pMag. Under blue light irradiation, these two parts undergo specific blue light dependent heterodimerization and assemble into complete T7 RNA polymerase, which acts on PT7 promoter (BBa_K3447005) and activates downstream gene expression. And the process is reversible, that is, when blue light is stopped, the dimerized T7 RNA polymerase dedimers and loses its function.

In our project, we use this part to form a complete T7 RNA polymerase by dimerizing it with T7CT under blue light. (链接104+f09+104+f10+001+b17)
