Cloned DNA: Escherichia coli lac repressor gene (lacI)
Escherichia coli lac Z gene (lacZ); fragment lacking codons 11-41 (lacZΔα)
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: Chloramphenicol (cam)
Replicon: Escherichia coli plasmid p15A origin
Host range: Escherichia coli
Parental clone: pACYCDuet-1Ωtac
Further information: The plasmid was created by cloning the E. coli lacZΔα fragment as a BamHI-NcoI fragment into the pACYCDuet-1Ωtac 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 pACYCDuet-1 plasmid.
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-omega 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 LT726840.1.
Both the 5' and the 3' end of the E. coli lacZΔα fragment were sequenced by BCCM/GeneCorner.
Name mentioned in Borloo et al. (2007) is pB2HΔα.
