Cloned DNA: Nicotiana plumbaginifolia catalase 1 cDNA (CAT1); fragment (CAT1f)
Promoter: Phage T7 gene 10 promoter (T7g10)
Phage T3 promoter
Escherichia coli lac operon promoter
binding site:
Terminator: -
Selection marker: Ampicillin (amp)
Replicon: Escherichia coli plasmid pMB1 origin
Phage f1 origin
Host range: Escherichia coli
Parental clone: pBluescriptIIKS+
Further information: The plasmid was constructed by inserting a 1064 bp fragment, containing the 3' region of the Nicotiana plumbaginifolia (tobacco) catalase 1 coding sequence (CAT1), into the EcoRV opened pBluescriptIIKS+ vector.
When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727072.1.
The nucleotide sequence of the pBluescriptIIKS+ vector corresponds with the Genbank accession number X52327.1. pBluescriptIIKS+ differs from pBluescriptIIKS- in the orientation of the f1 origin.
The nucleotide sequence of the N. plumbaginifolia CAT1 cDNA corresponds with the Genbank accession number Z36975.1.

Punctuation indicates reading frame.
Authenticity test: Restriction enzyme pattern analysed at GeneCorner: AvaI, BamHI, EcoRV, HindIII, KpnI and XmnI.

As compared to the compiled nucleotide sequence, the restriction site analysis pattern revealed that BamHI cuts three times instead of two times, resulting in fragments of approx. 200 bp, 1000 bp and 3000 bp respectively. Consequently, the plasmid seems to be 100 à 150 bp larger than theoretically expected, probably due to a larger 3' UTR part of the insert. The compiled nucleotide sequence has not been adapted accordingly.
