Further information: The plasmid was constructed by inserting the hybrid rat-human catalase cDNA as a NcoI/HindIII fragment from pCMVrhCAT into the EcoRI digested pCAGGS vector (all sites were filled in with T4 polymerase).
The fragment from the ATG to the PvuII site originates from rat, the fragment from PvuII to the termination codon originates from the human catalase gene.
pCAGGSrhCAT is useful for highly efficient expression of the hybrid rat-human catalase under the control of the chicken β-actin/rabbit β-globin hybrid promoter (AG) and the human CMV-IE enhancer in various mammalian cells.
The AG promoter sequence consists of the chicken β-actin promoter, the first exon and part of the first intron (that seems to have a strong enhancer-like activity) linked to a rabbit β-globin fragment, consisting of a 3' part of the second intron (inclusive a branch point which is required for normal splicing reactions) and a 5' part of the third exon.
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 LT727343.1.
Other name of the plasmid is pCAGGS/r-h-catalase.

Authenticity test: Restriction enzyme pattern analysed at GeneCorner: BamHI, EcoRI, EcoRI/PstI, EcoRI/XhoI, PstI, PvuII/XmnI and XhoI.

Although we could determine non-intensive bands on the agarose gel corresponding to the expected fragments for the EcoRI/PstI and EcoRI/XhoI digestions, the presence of the EcoRI site remains questionable. Theoretically, the EcoRI site should be present, being the result of the EcoRI/NcoI ligation after filling-in the two sites. However, the sequence analysis results of the Department of Molecular Biology (Ghent University, Belgium) revealed the nucleotide sequence 'GAATC' instead of 'GAATTC' at the EcoRI/NcoI fusion. Assuming that we might be dealing with a mix of DNA with (minority) and without the EcoRI site, BCCM/GeneCorner tried to purify the culture via single colony, selecting for the clear presence of the EcoRI site; without result however.
