pTYB1载体简介

pTYB1 is an E. coli plasmid cloning vector designed for recombinant protein expression. It contains the pMB1 origin of replication from pBR322 and is maintained at a similar copy number to pBR322; in addition, pTYB1 also contains an M13 origin of replication. The multiple cloning site (MCS) is positioned to allow translational fusion of the Sce VMA intein tag to the C-terminus of the cloned target protein (1). The chitin binding domain (CBD) from B. circulans, fused to the C-terminus of the intein, facilitates purification of the intein-target protein precursor. Transcription of the gene fusion is controlled by the inducible T7 promoter, requiring E. coli strains containing integrated copies of the T7 RNA polymerase gene [e.g., C2566, C2833 or BL21(DE3)] for expression. Basal expression from the T7 promoter is minimized by the binding of the Lac repressor, encoded by the lacI gene, to the lac operator immediately downstream of the T7 promoter (3). Translation of the fusion utilizes the translation initiation signal (Shine Dalgarno sequence) from the strongly expressed T7 gene 10 protein (φ10). pTYB1, pTYB2, pTYB3, and pTYB4 are identical except for the MCS regions (opposite page). All four vectors contain either an NdeI (pTYB1 and pTYB2) or NcoI (pTYB3 and pTYB4) siteoverlapping the initiating methionine codon of the intein fusion gene.  The N-terminal cysteine residue (“Cys1”) of the intein is shaded. Enzymes with unique restriction sites are shown in bold type. Location of sites of all NEB restriction enzymes can be found on the NEB web site (choose Technical Reference > DNA Sequences and Maps). Restriction site coordinates refer to the position of the 5′-most base on the top strand in each recognition sequence. Open reading frame (ORF) coordinates are in the form "translational start – translational stop”; numbers refer to positions on the top (clockwise) strand, regardless of the direction of transcription and include the start and stop codons. Component genes or regions of fusion ORFs are indented below the ORF itself. pMB1 origin of replication coordinates include the region from the -35 promoter sequence of the RNAII transcript to the  RNA/DNA switch point. For the M13 origin, the arrow shows the direction of synthesis of the (+) strand, which gets packaged  into phage particles. bla (ApR) gene coordinates include the signal sequence.
