Cloned DNA: Saccharomyces cerevisiae tryptophan 1 disruption cassette (TRP1)
Promoter: Escherichia coli lac operon promoter
binding site:
Terminator: -
Selection marker: Ampicillin (amp)
TRP1; auxotrophic
Replicon: Escherichia coli plasmid pMB1 origin
Host range: Escherichia coli
Saccharomyces cerevisiae; trp1(-), integrative
Parental clone: pUC9HStop; pJH-W1
Further information: The plasmid was constructed by inserting a 821 bp EcoRI (filled in with Klenow DNA polymerase) - PstI (blunted with T4 DNA polymerase) fragment of pJH-W1, containing the S. cerevisiae TRP1 auxotrophically selectable marker gene, into the unique HindIII site (filled in with Klenow DNA polymerase) of pUC9HStop, a pUC9 derivative differing in the sequence of the multicloning site.
This is an integrative yeast plasmid designed for gene disruption purposes. The disruption cassette consists of the TRP1 gene, flanked by termination codons in all three reading frames and restriction sites. The termination codons prevent read-through from the remaining sequences of disrupted genes and those of the selectable disrupting fragment; in this way, possible artefactual phenotypic effects caused by fortuitous hybrid proteins are avoided.
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 sequences at the junctions were experimentally verified by Dr G. Berben prior to deposit at BCCM/GeneCorner. The sequence at the PstI-HindIII fusion did not completely correspond with the theoretically expected sequence.
