Mj-tRNA with amber anticodon for incorporating ncAA in E.coli
For incorporating unnatural amino acids into a protein, a orthogonal tRNA:Synthetase-pair is needed which does not crossreact with the cognate tRNA:Synthetase-pairs. This tRNA can be assembled with a variety of synthetases into a plasmid to incorporate ncAA in E.coli.
Usage and Biology
This tRNA derives from the wild type tyrosyl Methanococcus janaschii tRNA:Synthetase pair. It was proven to not crossreact with the cognate E.coli tRNA:synthetase-pairs (A Genetically Encoded Photocaged Tyrosine - Schultz et al, 2006).
The tRNA is used together with a tRNA-Synthetase. It has been proven to work with (enter links for parts)
- wild type Tyrosine-synthetase (Y-RS)
- AzF-RS
- CNF-RS
- Iodo-Y-RS
- 5HTP-RS
- Nitro-Y-RS
by [http://2014.igem.org/Team:Austin_Texas iGEM-Team Austin, Texas 2014].
[http://2016.igem.org/Team:Aachen iGEM-Team Aachen 2016] used the tRNA to successfully incorporate DMNBS E.coli with their newly designed DMNBS-RS.
This tRNA has an amber anticodon for incorporating the ncAA in response to an amber codon. It has been used previously with an amberless E.coli strain as well as BL21 DE3 gold.
