WebbThis vector was composed of pTrc99C (Amann et al. Gene 69 (1988) 301-315) and a modified signal peptide sequence-free PhoA DNA such that the structural gene for PhoA is in the correct reading frame for the translation initiation codon of pTrc99C and immediately on the 5th 'End of the PhoA structural gene (without signal sequence) an NcoI interface … WebbThe expression cassette containing the Pr promoter of E. coli λ phage under cI repressor regulation and the nucleotide sequence coding for barnase and barstar structural genes were merged into the plasmid pTN441, which was used for large-scale barnase production. The phoA signal peptide was used to express the target protein into cell periplasm.
