摘要
We have developed a single-plasmid system for the efficient bacterial, expression of mutant proteins containing unnatural amino acids at specific sites designated by amber nonsense codons. In this system, multiple copies of a gene encoding an amber suppressor tRNA derived from a Methanocaldococcus jannaschii tyrosyl-tRNA (MjtRNA(CUA)(Tyr)) are expressed under control of the proK promoter and terminator, and a gene encoding the desired mutant M. jannaschii tyrosyl-tRNA synthetase (MjTyrRS) is expressed under control of a mutant glnS (glnS') promoter.
