Pyrrolysine analogs as substrates for bacterial pyrrolysyl-tRNA synthetase in vitro and in vivo

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.
