O-Methyl-L-tyrosine tRNA synthetase

This Part encodes the tRNA for nonnatural aminoacid O-Methyl-L-Tyrosine and its synthetase.

The orthogonal pair from the "Expanded Genetic Code Measurement Kit" by the iGEM team Austin Texas 2014 was used as template.

Usage

The orthogonal pair for amber supression consists of the tRNA with an anticodon complementary to the amber stop codon and an aminoacyl RNA synthetase (BBa_K1976021) specifically loading the tRNA with the non-natural amino acid. The occurence of O-methyl-L-tyrosine does not stop the translation of the immunoprotein.
