Abstract

Pyrrolysine-tRNA^Pyl complex is produced by pyrrolysyl-tRNA synthetase (PylRS). In this study, we investigated the substrate specificity of Desulfitobacterium hafnience PylRS. PylRS incorporated various L-lysine derivatives into tRNA^Pyl in vitro. In addition, the PylRS/tRNA^Pyl pair introduced these lysine derivatives into the recombinant protein by the Escherichia coli expression system, indicating that this PylRS/tRNA^Pyl pair can be used in protein engineering technology.
