Design Notes

The 6xHis tag was added to the mleR coding sequence during part design, as we wanted to characterize the toxin-antitoxin system and thus had to derive a parameter for its quantity; we, therefore, needed to perform protein quantification and believed adding a 6xHis tag to be the most straightforward method of achieving this end. The sequence of mleR and 6xHis was then reversed, as we would use it in the composite part BBa_K4130, which uses a T7 promoter to overexpress mleR; the T7 promoter is optimal when reversed, so we adjusted this part's direction in response to this fact.

Unfortunately, the sequence features view tool does not reflect the fact that this part is reversed; attached below is a benchling screenshot of how the sequence features should look.
