OrthoRep expression engineering paper accepted

Congratulations to Ziwei and Arjun on their work engineering the expression systems of OrthoRep. This work, just accepted at ACS Synthetic Biology, shows that new promoters and hard-coded polyA tails can increase the expression of genes on the orthogonal plasmid by up to ~40-fold over what we could previously attain, almost reaching the strongest expression levels of genomically-encoded genes. Now, OrthoRep should be able to evolve genes requiring low or high levels of expression, and anything in between!
