wild type tyrosyl synthetase for use in E.coli with amber anticodon and Y32G

This is a DMNBS-synthetase to be used as a orthogonal synthetase in E.coli. This part can be used together with the cognate tRNA BBa_K2020042 to incorporate DMNBS in response to an amber stop codon.

Usage and Biology

Incorporation of DMNBS

Assembly in a synthetase plasmid for incorporation of ncAA

pACYC derived plasmid with Mj tyrosyl synthetase and cognate tRNA

Most synthetases are used with low copy plasmids (e.g. pACYC). Assemble the tRNA and the synthetase into a low copy plasmid, each one with an own promoter and one terminator for both. (See picture). If your application is not for incorporation into a protein but for use with a second plasmid, make shure to use replicons from different incompatibility groups, eg. ColE1 and p15A and different selection markers. A second plasmid could be the flourescent reporter plasmid pFRY for the purpose of determining fidelity and efficiacy of synthetases for ncAA.
