Cloned DNA: Escherichia coli lac repressor gene (lacI)
Escherichia coli lac Z gene (lacZ); fragment lacking codons 788-1023 (lacZΔω)
Promoter: Phage SP6 promoter
Phage T7 gene 10 promoter (T7g10)
Escherichia coli lac operon promoter
Escherichia coli lac repressor promoter (lacI)
Escherichia coli hybrid tryptophan/lacUV5 promoter (tac)
binding site:
Ribosome binding site (RBS) of the Escherichia coli lac Z gene (lacZ)
Terminator: Phage T7 gene 10 terminator (T7g10)
Selection marker: Ampicillin (amp)
Replicon: Escherichia coli plasmid pMB1 origin
Phage f1 origin
Host range: Escherichia coli
Parental clone: pETDuet-1ΔSphIΩtac
Further information: The plasmid was created by cloning the E. coli lacZΔω fragment as a BamHI-NcoI fragment into the pETDuet-1ΔSphIΩtac vector. This parental vector was created by inserting the tac promoter as an EcoRV-PstI fragment from pALTER-Ex1, after deleting the BamHI restriction site, in the pETDuet-1 plasmid with the SphI site deleted.
The plasmid can be used in bacterial two-hybrid systems which are based on trans complementation of β-galactosidase (e.g. by co-expression with pB2H-delta-alfa in lacZ(-) strains).
The T7 terminator is not functional for this construct.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT726841.1.
Both the 5' and the 3' end of the E. coli lacZΔω fragment were sequenced by BCCM/GeneCorner. The length of the plasmid described in the sequence file that BCCM/GeneCorner obtained from the depositor does not correspond to the length described in Borloo et al. (2007). Furthermore, the sequence file also lacks codon 788 of lacZ, in contrary to Borloo et al. (2007).
Name mentioned in Borloo et al. (2007) is pB2HΔω.
