RS/tRNA Pair Usage Information
This RS/tRNA pair was evolved with MAGE[ multiplex automated genome engineering]. The evolved pair has been shown to have a 25-fold higher expression of pAzF in GFP[3UAG] compared to the progenitor enzyme (pAcFRS). This pair has also been shown to be promiscuous, and specifically also incorporates pAcF.
