xynD, which produces xylanase
T7 promoter is a very specific promoter which is transcribed only by specific T7 RNA polymerase which can activate downstream gene expression after being combined.
Usage and Biology
In our project, we divided T7 RNA polymerase into two parts, respectively called T7NT (链接) and T7CT (链接) and attached on the nMag and pMag. Under blue light irradiation, these two parts undergo specific blue light dependent heterodimerization and assemble into complete T7rna polymerase, which acts on PT7 promoter and activates downstream gene expression. And the process is reversible, that is, when blue light is stopped, the dimerized T7RNA polymerase de-dimers and loses its function.
The kanR gene is a relatively common type of resistance gene in molecular cloning, and it is also very common in commercial plasmids. In the process of constructing plasmids, we will choose kanamycin-resistant vectors, so we no longer too much detail on its mechanism of action.
Design
Design Notes
We added some synonymous mutations to avoid part rules.
