Circular map: p5021.pdf
Status: GeneCorner core plasmid
Cloned DNA: Nicotiana plumbaginifolia manganese superoxide dismutase cDNA (MnSOD)

binding site:
Terminator: Agrobacterium tumefaciens Ti-plasmid octopine synthase terminator (ocs)
Selection marker: Neomycin (neo; kanamycin (kan))
Streptomycin (Sm; spectinomycin (Sp))
Replicon: Escherichia coli plasmid pMB1 origin
Pseudomonas plasmid pVS1 origin
Host range: Escherichia coli
Plant cells
Parental clone: pSOD1; pGSJ780A
Further information: The plasmid was constructed by inserting the 956 bp HpaI-SmaI fragment of pSOD1, containing the Nicotiana plumbaginifolia manganese superoxide dismutase (MnSOD) cDNA, into the ClaI (filled-in) opened pGSJ780A vector. The orientation of the inserted fragment is sense relative to the CaMV promoter.
pEX1SOD was designed for mitochondrial MnSOD overproduction under control of the CaMV promoter.
The plasmid contains a neomycin resistance cassette consisting of the Agrobacterium tumefaciens Ti-plasmid nopaline synthase (nos) promoter, the neomycin (neo, nptII) resistance gene, and the A. tumefaciens Ti-plasmid octopine synthase (ocs) terminator, that can be used for selection of transformed plants.
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 the MnSOD cDNA corresponds with the Genbank accession number X14482.1.
Name mentioned in Bowler et al. (1991) is pMitSOD.

Authenticity test: Restriction enzyme pattern analysed at GeneCorner: BamHI/ClaI, BglII, EcoRV/NheI, HindII, HindIII/SacII, HpaI/SmaI, NdeI and PvuII.

The PvuII site at position 12718 could not be experimentally confirmed. The compiled nucleotide sequence has not been adapted accordingly.
