To construct plasmid pSepT, the full-length gene encoding tRNA^Sep
was constructed from overlapping oligonucleotides and ligated immediately downstream of the lpp promoter in pTECH (Bunjun et al., 2000) using EcoRI and BamHI restriction sites.
This plasmids is delivered in wild-type DH5alpha cells.
To prevent possible enzymatic dephosphorylation of O-phospho-L-serine (Sep) in vivo, the gene encoding phosphoserine phosphatase (serB), which is catalyzing the last step in serine biosynthesis, was deleted from Escherichia coli strains Top10 (Top10∆serB - Addgene #34928) and BL21 (BL21∆serB - Addgene #34929). These strains are required hosts when using this plasmid.
Addgene has sequenced a portion of this plasmid for verification.
