Construction of BBa_K567015
Rational design of MetRS: we have obtained a truncated MetRS without anticodon recognition domain. The structure of the truncated protein is shown below. This modified MetRS can charge tRNAMet without recognizing its anticodon.
fig. This design is based on the crystal structure of methionyl-tRNA synthetase complex with tRNA (PDB ID：2CSX). We have superimposed the crystal structure of methionyl-tRNA synthetase from E.coli and obtained the overlay structure after kinetics optimization. Above is the picture showing E.coli methionyl-tRNA synthetase with (left) and without (right) anticodon recognition domain. The picture proposed that E.coli methionyl-tRNA synthetase will lose the ability to bind tRNAMet anticodon if anticodon recognition domain is deleted, thus losing anticodon specificity while maintaining aminoacylation ability. We have built the truncated MetRS, PT7-metGN (BBa_K567015), based on this design.
