metY-CGA
This biobrick is constructed by mutating the anticodon of tRNAMet to TCG (base pairing codon CGA). This tRNA can transfer fMet to CGA when it is used as the start codon. KanR gene with start codon substituted for CGA is used to testify the function of metY-CGA. When this biobrick and metGM(BBa_K567014) or metGN(BBa_K567015) are co-transformed into the cell, the cells can survive on the LB Kan plate.
Construction of BBa_K567016
metY-CGA: We have cloned operon metY containing tRNAMet from E.coli to pACYC184. The anticodon of tRNAMet was mutated to TCG (base pairing codon CGA).
Characterization of BBa_K567016
When this part, MetRS PT7-metGN (BBa_K567015)(or MetRS PT7-metGM (BBa_K567014)) and KanR (BBa_K567020) are co-transformed into the cell, the cell is expected to survive Kanamycin.
Cell growth shows that the cells show Kanamycin resistance only when both modified MetRS (metGN) and modified tRNAMet(metY-CGA) are transformed into the cell, proving that metGN works well.
